    FIELD OF THE INVENTION
    This descriptive report concerns patient monitoring systems. More particularly, this descriptive report concerns a patient monitoring system and method using dual display bedside monitors that are connected to a hospital information system and have the ability to simultaneously display waveforms and vital statistics real-time patient monitoring as well as providing display for local and remote software applications. BACKGROUND OF THE INVENTION
    Conventional patient bedside monitors are connected to various vital statistics measurement/monitoring devices and display real-time patient vital statistics such as pulse rate and blood pressure, among other variables, continuously. Usually displayed vital statistics are not recorded on the monitor and consequently, once they disappear from a display, the information is not further cached, temporarily stored or otherwise stored and therefore lost. In cases where the monitor records displayed information and presents it in the form of patient health trends, the real-time vital statistics display is dimmed.
    In a hospital environment, patient-specific information such as blood test reports and X-ray reports, among other data, is generated at locations far from the patient's bedside. Such information is usually stored in the hospital's information system and can be accessed by healthcare professionals when required from a central server. Healthcare professionals may have to carry the information in paper form in order to study/compare it in context with real-time patient vital statistics. As the volume of paper being transported by the healthcare professional increases, the chances of delay in diagnosis/treatment due to delay in finding a relevant piece of information also increase. Also, some piece of patient information may not be available to the healthcare provider at any time and may cause a delay or error in diagnosis and treatment.
    Consequently, there is a need for a patient bedside monitor that is capable of connecting to the hospital information system and displaying all information related to a specific patient. There is a need for a bedside monitor that can display all patient-related information available with the hospital at the same time and without obscuring the real-time display of the patient's vital statistics. There is a need for an intelligent bedside monitor that can provide analysis of patient health information over a specified period of time matching any set of predefined criteria by a healthcare professional,
    In addition, there is a need for a multi-purpose display that can be partially under the control of the user, but that does not replace or compromise critical functions, such as displaying monitored key physiological parameters or issuing alarms in relation to monitored events. The multi-purpose display enables a single physical display unit to perform multiple functions, thus avoiding taking up excessive hospital room space by additional display units, while not impairing, sacrificing or compromising the core function of a physiological display.

    This descriptive report provides a dual-display monitor that can be configured on a patient bedside to provide aggregated patient-related medical information along with real-time patient vital statistics. One of the two views continuously shows real-time patient monitoring information while the other is used to display information such as when medications were administered, show lab results in reference to vital signs and provide access to other remote hospital applications, typically accessible only via separate data terminals. The dual display monitor is connected to the hospital information system and has the ability to display local software applications and remote software applications via remote display software, such as software made available by Citrix™. Furthermore, the dual display monitor can be connected to a central monitor configuration that can include up to four additional displays. These additional displays can be used to monitor more patients, display additional data and/or host other applications.
    This descriptive report is aimed at multiple modalities. The following disclosure is provided in order to enable a person having common knowledge in the art to practice the invention. The language used in this descriptive report should not be interpreted as a general contradiction of any specific modality or used to limit the claims beyond the meaning of the terms used in them. The general principles defined in this document can be used in other modalities and applications without departing from the spirit and scope of the invention. Also, the terminology and phraseology used are for the purpose of describing exemplary modalities and should not be considered limiting. Thus, this descriptive report is to be given the broadest scope encompassing numerous alternatives, modifications and equivalences consistent with the disclosed principles and resources. For purposes of clarity, details relating to technical material which is known in the technical fields relating to the invention are not described in detail in order not to unnecessarily obscure the present invention.
    Figure 1 is a block diagram illustrating an environment in which the dual display monitor is used in accordance with an embodiment of the present invention. Dual display monitor 102, comprising a first display monitor 110 and a second display monitor 112, is installed on a patient bedside and is connected to the patient monitoring system 101 via an included display manager 105. in said patient monitoring system 101. In various embodiments, the patient monitoring system 101 includes ports for a plurality of measurement devices, which include, but are not limited to, ports for blood pressure monitoring systems, heart rate monitoring systems and for pulse oximeter monitoring systems. The display manager 105 interfaces with a local display structure 103 and a remote display structure 104, both of which are also included in the patient monitoring system 101. The remote display structure 104 communicates with a remote application 107 which in turn collects information from a database 108 and a hospital information system (HIS) 106. The HIS 106 has access to data received from a plurality of laboratories 109, 109A. Data received from laboratories 109, 109A includes blood test reports, X-ray scan reports, among other data. The patient monitoring system 101 is also directly interfaced with said database 108 and consequently with the HIS 106.
    Patient monitoring information is provided to database 108 where the information is sorted and, in one embodiment, a subset of the information is provided to hospital information system 106. First display monitor 110 displays vital patient statistics real-time such as obtained by the patient monitoring system 101. Real-time patient statistics comprise, for example, numerical data (such as heart rate, systolic blood pressure and cardiac output), alarm states (when a current condition of the patient violates a pre-configured alarm state) and other technical and medical condition (such as anomalistic weakening of pulse oximeter signal or disconnection of ECG electrode(s).
    Database 108 comprises at least one storage memory that resides locally within dual display monitor 102 as well as at least one storage memory external to monitor 102 residing in close proximity or remotely from monitor 102. Thus, in one embodiment, some or all vital patient statistics data, communicated and displayed in real time by the first display monitor 110, is also stored in local data storage residing on the dual display monitor 102. This locally stored patient data, in one modality, are used to create trend views and to allow analysis of alarm data in the clinical context. In one embodiment, at least a portion of the total patient vital statistics data stored in local data storage residing on the dual display monitor is also available for submission to the hospital information system. Additionally or in alternative modalities, some or all of the vital patient statistics data is communicated over a network for storage in a database that is external to the dual display monitor 102. The storage capacity of an external database as this is typically great for accumulating data over a long period of time. Persons of ordinary skill in the art should realize that the external database may reside on a computer/server in close proximity to the dual display monitor 102 and/or on a computer/server away from the dual display monitor 102 .
    Data from the external database is exported to hospital information system 106 using standard output formats such as HL7, Medibus. In one embodiment, data from the external database is pushed to the hospital information system 106 at predetermined intervals. Additionally, the data is also accessible via queries to the external database, which in one modality can be customized.
    The second display monitor 112 displays aggregated information from database 108 and hospital information system 106. Information such as patient health trends, drug effects on patient vital statistics, laboratory results, and so on. data, is displayed on the second display monitor 112, provided by at least one or more underlying local or remote software. Consequently, the information displayed on the second display monitor 112 enables healthcare professionals to understand and analyze the patient's progress and response to drugs and, consequently, respond effectively to changes in the patient.
    In one embodiment, local and remote software applications accessed on dual display monitor 102 enable viewing of patient data stored in the external database in a mode that enhances bedside patient monitoring functionality. For example, an ECG waveform analysis application, hosted on monitor 102, allows waveform recordings over the past 72 hours to be analyzed, edited, uploaded and re-stored. In another example, a database application enables retrieval of readings from labs 109 and directs them to display. Persons of ordinary skill in the art should realize that such software applications may reside locally or be hosted on a separate bedside monitor, central workstation, or physician's office PC. In each case the patient data is retrieved from the external database and the editing session is performed on the connected computer accordingly. Additionally, in additional embodiments, the local and remote software applications accessed on the dual display monitor 102 also comprise applications other than those specifically listed to provide patient monitoring functionality. For example, such software may be an entertainment, Internet or other network connectivity, or a patient education application or an email or video conferencing application or any other value-added application that would advantageously be apparent to people of ordinary knowledge. in technique. In one modality, fixed screen zones are established for patient applications. For example, patients are not allowed to cover vital signs displays or they are restricted to use the second display monitor 112, in one modality, for email, video conferencing or other patient activities.
    In one embodiment, dual display monitor 102 may be enabled in patient mode or healthcare professional mode. In patient mode clinical settings cannot be changed, but a controlled list of approved software applications, such as entertainment or patient education, can be run. The monitor is in patient mode unless a healthcare professional is in the room. So, for example, when the patient is in the room and not being seen, the monitor will typically be in patient mode. Mode can be changed remotely by a healthcare professional. To switch to healthcare professional mode the monitor is enabled to receive a credential, password or RFID badge. In one modality, patient mode context-sensitive incapacitation or minimization is enabled. Thus, in the event of a change in clinical status [eg, a certain class of alarm (high priority)] the patient's application is disabled or minimized until clarified by a healthcare professional. Ideally, this would be configurable by the healthcare professional by alarm type or alarm class.
    The dual display functionality of monitor 102 of the present invention enables optimization between displaying real-time patient monitoring data and therefore related alarm contexts and displaying information from local or remote software applications accessed on monitor 102.
    Optimization is achieved by providing suitable real-screen situation through a plurality of scenarios, such as in the various modalities set out below, wherein in a first modality, the first display monitor 110 is used for full-time real-time monitoring while the second display monitor 112 is used for full-time hosted application viewing. In another embodiment, the first display monitor 110 and the second display monitor 112 are both available for viewing hosted application, but the first display monitor 110 is reserved for real-time monitoring when an "event of importance" occurs. Also in another embodiment, the first display monitor 110 and the second display monitor 112 are both available for monitoring during an "important event".
    It should be noted that the presently disclosed system enables critical patient data, defined as data that a) is indicative of a patient's health status requiring immediate attention from a healthcare professional or is otherwise time critical, b) is indicative of a patient's health status that should be brought to the attention of a healthcare professional, but which may not be time critical, and/or c) are designated by a healthcare professional as requiring substantially constant display, to be displayed alongside non-critical data, defined as data that is not critical patient data, without compromising the display of critical patient data. It should additionally be noted that the functionality described in this document is performed by a controller implementing a plurality of instructions, stored in local memory or away from the display, and executed by at least one processor.
    In another modality, there is only one display, but a part is pre-allocated as application display area. In another modality, there are two, three, four or more display regions controlled separately in a single physical display. In another modality, there are two, three, four or more display regions controlled separately in two or more physical displays. It should be noted that a display area or region can be a region of pixels located in one or more physical displays.
    Also in another modality, there is only one display and applications can occupy the entire screen area, but cede control during an "important event". In this case, it is possible that a healthcare professional is running a software application and hiding/masking some or all of the monitor's vital real-time information when a patient's condition changes. In such cases, in one modality, the monitor is enabled to minimize all applications for certain types of patient events. Thus, certain events (alarms of a certain type or priority) automatically minimize all applications thus displaying the monitoring message. In another modality, the application remains running, but a message (which must be replied to) is posted on top of any and all applications. If the message is not replied to then the application is automatically minimized. Alternatively, all applications can be automatically minimized after a configurable time expires. Thus, in case an application user leaves the application running (blinding some or all of the real-time vital signs monitoring functionality), the application is minimized after a period of inactivity. In various modes, the inactivity period is set to 1, 3, 5, 15, or any other value determined by the user. For example, assuming an inactivity threshold of 3 minutes, if a user logs into an application and enters data for 5 minutes the application will not be minimized because of activity. When the user is called away from the monitor, after 3 minutes the application will be automatically minimized.
    Persons of ordinary skill in the art should realize that an "event of importance" can be a plurality of predefined states/scenarios/thresholds/rules. In one modality, an "importance event" is defined per user (such as, for example, heart rate > 140 bpm, systolic blood pressure > 150 or < 90). In another modality, an "event of importance" is defined using an arbitrary complex set of rules to define when non-critical applications should yield to real-time monitoring. Also in another modality, "event of importance" is based on alarm status (such as: any alarm, any high priority alarm, and any medium or higher priority alarm). In yet another modality, the "event of importance" is capable of being rejected by a user. Thus, a user can cancel and run an application when deciding that an alarm is not truly real.
    In one modality, functions related to "important events" are managed by a software module, referred to below as the 'clinical context manager'. The clinical context manager monitors the patient's status and continually compares it to rules that have been established (default or user-defined). In this way, the context manager indicates hosted software applications to be displayed or minimized.
    Additionally, based on the patient's state, the context manager can initiate additional activities, which can be standard behaviors or they can be configured by the user. They can be configured based on alarm type or severity, or they can be based on clinical indexes that are currently being monitored. The additional activities that are started can be of several different types, such as, but not limited to, the following: a) recording additional data in the local or external database b) starting an application that retrieves additional information from a database. local or external data and presents the current status in a clinical context in the application area. 1. For example, where a patient's blood pressure is gradually dropping, the change in the patient's state is noticed by the clinical context manager and an application is launched that retrieves the complete blood pressure history and graphically represents the recent change in context in the recording history. These data are displayed in the application window. 2. Where a patient is a diabetic, a user can select a default diabetes clinical context for this patient (or it can be selected automatically if the diabetes diagnosis was retrieved from a health recording). These activities are configurable per user. Part of the standard "diabetes" clinical context rules may be to retrieve the most recent blood sugar reading in the case of successive low blood pressure readings. In this case, multiple low readings would trigger an application to retrieve extended blood pressure history and extended laboratory and blood draw data and present this data in an application window. A clinician who was then checking on the patient would see the current monitoring status and pertinent data presented in a clinically appropriate way. 3. In another example, the primary display is showing ECG, SpO2 and NIBP values for a patient. Initially, the patient is in normal sinus rhythm, but over time begins to develop an increasing number of abnormally conducted pulses. The Clinical Context Manager launches a trend analysis application (either locally on the monitor or on a remote workstation) that renders a trend graph of the number of abnormal heartbeats versus time for the last few hours. This trend will draw the health professional's attention to a parameter that the clinical context manager has determined to be changing. 4. Also in another example, the Clinical Context Manager will launch a trend analysis application if a patient's average heart rate increases by more than 15%. In this example, the trend analysis application will display the patient's heart rate for the last 6 hours and render the data at 30 second resolution with real-time updates.
    Figure 2 illustrates a patient monitoring system as shown in Figure 1 that is employed, in one embodiment, to support and/or control dual display functionality. The patient monitoring system 200 supports the connection of two display units such as video display units (VDU), liquid crystal display screen (LCD), among any other types of displays known in the art.

    The dual display system architecture enables improved data access and an integrated display of data from multiple sources. In various modalities the display's graphical user interface (GUI) comprises a plurality of widgets with which a user (a healthcare professional or a patient) can interact. In one modality, widgets are displayed as borderless windows or icons. In one modality, widgets are set to a predefined location. In one modality, widgets are not resizable. Examples of widgets comprise widgets to display patient health trends, lab data, event activations, alarm history, clinical data, treatment protocols, launch clinical applications, launch hospital applications, or print data.
    In one modality, Windows Dynamic Network Access (WinDNA) provides access to custom applications running at pinned screen locations through dynamic network access (DNA). Thus, in one embodiment, DNA is a software application that allows external entity applications (such as, but not limited to, HIS) running on another computer to host a session on the bedside monitors. The data to trigger the display and to interact with the user in the display is exchanged through a network configuration.
    Thus, WinDNA allows users to see and control Windows applications on display. Input to WinDNA can be done using a mouse, a keyboard and via the touch screen. In one embodiment, a thin client, built into the DNA-enabled display, allows users to launch applications installed on the server using the hospital's existing network infrastructure.
    Figure 6 illustrates a block diagram of the 600 power configuration of a patient monitoring system that is employed, in one embodiment, to support and/or control dual display functionality. In one embodiment, the power configuration 600 includes a power supply component 610 and a backplate component 640. The power supply component 610 and the backplate component 640 are interfaced via two separate connections . The first connection is an interface between a power supply I/F connector 642 on backplane component 640 and a backplane I/F connector 612 on power supply component 610. The second connection is an interface between a connector SDLC 644 on the 640 backplane component and an SDLC 614 connector on the 610 power supply component.

    Referring to Figure 7, a display 701 comprises a data display region 702, a plurality of data access keys 704, 705, 706, 707, and a pinned region 703 that displays data accessed when the data access keys data 704, 705, 706, 707 are activated. For example, when a trending key 704 is pressed or pressed, a command is transmitted to a virtual PC 708 that causes an application corresponding to conducting trend analysis to perform and access, retrieve, or otherwise obtain data from a database data 709. The accessed data is then communicated to a second server 710, which formats the accessed data for display in region 703. In one embodiment, the display of region 703 is fully controlled by the second server 710. It should be noted that each one of the keys 704, 705, 706, 707 corresponds to running an application which is stored in the memory of virtual computer 708 and executed by a processor in virtual computer 708. In one embodiment, data access key 704, 705 , 706 or 707 for whichever application is running is highlighted to inform the user which application is being displayed. It should additionally be noted that the keys can be configured to make Virtual PC applications access data relevant to patient health trends, laboratory data, event activations, alarm history, clinical data, or protocols, to initiate lists of checks, to launch clinical applications, to launch hospital applications, or to print data.
    In one modality, keys are induced to be displayed by a monitor that, upon startup, accesses an XML configuration file that defines key location, size, graphic, text, which application executable on a remote PC is related to the displayed key , context parameters to pass, WinDNA behavior when starting, such as pinned, margin, border size, among other parameters.
    Referring to Figures 8 and 9, which are architectural block diagrams of dual display monitors, an upper layer application class is driven by display, window manager, and event manager objects. The event handler object is additionally dependent on various inputs, such as a mouse, cursor and keyboard.
    Figure 10 is a flowchart illustrating the events that happen upon activation of a widget on a display monitor. A widget, such as a trending, alarm, or other data access key, is activated at 1002. In one modality, widget activation triggers at 1004 an event that starts an application with respect to a specific patient. The started application runs in 1006 on a virtual processing machine (computer). The application extracts 1008 data from a classification database in which data obtained from bedside patient monitoring systems is stored. The extracted data is presented in 1010 in application user interface format on the display monitor via WinDNA. Exemplary Use I
    In exemplary usage, a 42-year-old male victim of a motorcycle accident is mechanically oxygenated in the Intensive Surgical Care Unit (SICU) of a large urban hospital. He suffered a ruptured spleen that was removed; fractured left leg, left arm, left ribs T6-9; and is currently suffering from respiratory and renal failure. During the first 48 hours of admission he required high concentrations of oxygen for severe hypoxemia that precipitated acute respiratory distress syndrome (ARDS). The critical trauma patient is diagnosed with multiple system organ failure and ARDS and is placed on a permissive hypoxia protocol to prevent further damage from oxygen toxicity because of the high fraction of inspired oxygen graduations (FiO2) in a ventilator.
    The physician recorded an order for an oxygen weaning protocol (permissive hypoxia); the patient is on a cardiac monitor with clinical agent application and mechanical ventilation with supplemental oxygen. Minimal FiO2 gradations are maintained (O2 concentration less than 40%) on the ventilator for improved patient outcome (no lung injury from prolonged high oxygen therapy) and a few days in SICU. The physician ordered oxygen weaning protocol is displayed on the dual display monitor when the protocol widget is triggered. The protocol can be displayed in the second or fixed region of the monitor such as "Keep SpO2 less than 92%, but greater than 88% when decreasing ventilator O2 concentration by 2% no more than once per hour".
    In one modality, this protocol is displayed in basic clinical agent format and may (or may not) flash alerts when SpO2 protocol levels are reached to speed nurse/respiratory therapist workflow and more efficiently generate patient care than by turn can decrease the number of days in SICU. Without protocol display, the nurse/therapist would have to locate protocols through time-consuming search across multiple files, and patient care and workflow would be less efficient. Exemplary Use II
    In another modality, a 78-year-old patient is awaiting ablation evaluation in the Critical Care Unit (CCU), and persists with frequent cases of atrial fibrillation (AFib) lasting over an hour. The patient is on the CCU for evaluation of LA ablation to treat chronic permanent atrial fibrillation. She is on a cardiac monitor with an ECG algorithm, oxygen in a nasal cannula at 2 L/min, and has a history of dizziness, shortness of breath, and fatigue.
    The physician recorded an order for AFib load protocol while awaiting results for ablation assessment. The patient was classified as Class II-A for AFib and takes 81 mg aspirin, 0.14 mg digoxin, and 50 mg atenolol daily. It has a peripheral IV maintenance line for access. The patient was safely treated pharmacologically for reversible cases of AFib. Her doctor has put her specific classification and evidence of complications into her treatment protocol. The following protocol displays on the dual display monitor whenever the ECG algorithm detects AFib and begins tracking whether the amount of AFib time is consistently present: "After 30 minutes of consistent AFib, they give 150 mg of amiodarone slow IVP (above 10 minutes) if PFTs with DLCO are on record, if no PFTS with DLCO, then give 20 mg/min of procainamide until a dose of 17 mg/kg is reached or until resolution of AFib or even bradycardia (whichever occurs first)". The dual display monitor will also flicker when the ECG rhythm returns to normal. Without the protocol display, the nurse would have to locate protocols through time-consuming search across multiple files and patient treatment and workflow would be less efficient. Exemplary Use III
    In another modality, a 6-year-old male was treated for alcoholic pancreatitis in the ICU of an urban hospital and suffered a heart attack. The patient is on a cardiac monitor with IV access. When the patient went into ventricular fibrillation (V Fib) and the cardiac monitor began to sound an alarm, the attending nurse selected the cardiopulmonary resuscitation (CPR) protocol key on the dual-display monitor. The dual-display monitor displayed the following: (1) the current Advanced Cardiac Life Support (ACLS) reference flowchart for decision making, (2) CPR medications calculated for this patient's current weight, and (3) a diagram of reference with index of your hospital component cart to help locate medications and supplies. From the start of CPR the on-screen ACLS reference card was used for decision making and saved valuable time as the physician did not need to locate his card. The medication list was also time efficient as it was clearly displayed and patient specific.
    As CPR progressed, the patient became more difficult to ventilate with a bag and mask, and the physician was unable to intubate. The decision was made to use a LAM device to ventilate the patient, but the respiratory therapist could not locate one in the component cart. Using the component cart's dual display and index monitor, the respiratory therapist was able to identify the location of the LAN device and so it could be used to ventilate the patient until an anesthesiologist could arrive to intubate. After 27 minutes of effective and efficient CPR, the patient was stabilized and placed on a ventilator.
    Using the physician's pocket ACLS card to direct care is the standard of care, but it slows down the process when the card is lost or difficult to read after aging. Viewing ACLS protocol adjacent to the cardiac monitor on the DNA monitor is more time-efficient during a critical procedure, allows for online medication calculations, and improves readability. Searching a cart for supply components is a slow process, and in the heat of the moment items not often used can become more visible. Without the on-screen display and component cart index, the LAN device would not have been found and effective ventilation could not have been performed, which could have altered the patient result. Exemplary Use IV
    In another modality, a cardiologist has a patient with complex chronic heart failure in the CCU with multiple intravascular lines in place on multiple medications to manage preload and afterload. The cardiologist intends to visualize and evaluate the effect of treatment options on hemodynamic indices. The patient is on a cardiac monitor with a DNA display, PA line and/or other device interfaces (such as USCOM) for continuous or occasional hemodynamic measurements.
    A 68-year-old patient with a seven-year history of chronic congestive heart failure presents with heart failure on both the right and left sides. Measurements are available for SVI, CI, RVSWI, LVSWI, PVR and SVR over a 24-hour period for a three-day course of medication administration. The physician wants to graphically represent the hemodynamic indices. Using the grid illustrated in Figure 11, the dual-display monitor interfaces with the cardiac monitor's data collection devices and graphically represents 1100 hemodynamic values. Without the data-grid display, the clinician would have to locate data through time-consuming search across multiple files and patient treatment and workflow would be less efficient.
    Consequently, dual-display monitors can be used by clinicians or healthcare professionals to access waveforms and physiological measurements, as well as real-time information related to the patient at the point of care (ie, patient bedside) at in order to provide fast and accurate diagnosis and treatment. Exemplary Use V
    A 62-year-old man is admitted to the emergency room because of a case of fainting at home. It is monitored while several different tests run. While he is being monitored the clinical context manager is alerted that he had two cases of cardiac pause events that lasted 2.6 and 3.1 seconds; each of these events is posted to the external database. The monitor is configured to launch an application that analyzes this data and retrieves the recommended clinical protocol which is to look for a cardiology appointment and consider an implantable defibrillator.
    When the clinician returns to check on the patient he discovers the application by displaying the recent event along with the suggested next steps.
    The foregoing examples are only illustrative of the many applications of the system of the present invention. Although only a few embodiments of the present invention have been described herein, it is to be understood that the present invention may be incorporated in many other specific forms without departing from the spirit or scope of the invention.
