CENTRAL MONITORING STATION CONFIGURABLE BY THE

FIELD OF THE INVENTION

This invention generally relates to patient monitoring systems. More particularly, the present invention relates to a system for monitoring patients using a dynamic central monitoring station that includes multiple touch screens on which the displayed information is configured by the user.

BACKGROUND OF THE INVENTION

A patient monitoring system is an electronic medical device that divides different vital signs of a patient, collects all measurements like cats, and then displays such data graphically and / or numerically on a display screen. Graphical data is continuously displayed as data channels on a time axis. Current patient monitoring systems are capable of measuring and displaying a variety of vital signs, including pulse oximetry (SpO₂), electrocardiography (ECG,

Electrocardiograph), invasive blood pressure (IBP,

Invasive Blood Pressure), Non-Invasive Blood Pressure (NIBP), EEG

.. '. i. 7. - /. YES. A ll V

<img file="MX337609B_D0006.tif" />

(EEG, Electroencephalograph), cofpora temperature_;y'¿ cardiac, capnography (CO₂), and breathing. Patient monitoring systems are also capable of measuring and displaying maximum, minimum, and average values ​​and frequencies, such as pulse and respiratory rates. Additionally, patient monitoring systems are typically equipped with audible and visual alarms to notify medical personnel of changes in the patient's status. The alarm parameters can be set by medical personnel.

Patient monitoring systems are positioned near hospital beds, typically in critical care units, where they continuously monitor the patient's status and can be viewed by hospital staff. Information gathered by patient monitoring systems is displayed locally by the bedside and, through the use of a wired or wireless network, is also often displayed remotely at a central monitoring station. The central monitoring station is a centrally located caregiver work area, typically within an intensive or critical care unit, which includes, but is not limited to, display screens, workstations, patient medical history, and some medicines. As long as individual patients are not cared for, the nursing staff is located at ctuw suri jtüjit · v³ Μ Μ11 themselves at the central monitoring station · donae,: - pi monitor the status of a crowd .... go - simultaneously through the display screens.

While the display settings of current central monitoring stations are effective in displaying the patient's vital signs and notifying medical personnel of changes, they are not without certain drawbacks. For example, current central monitoring stations are limited in scale in the number of patients for whom they can display vital statistics. For example, the most current systems are capable of displaying information for up to 16 patients. This number may be sufficient for some critical care units, but it would not be sufficient for larger critical care units or for possible use in non-critical units in which the number of patients monitored by a single station is larger. Therefore, there is a need for a central monitoring station with the ability to display individual information for a larger group of patients simultaneously.

The display screens included with current central monitoring stations typically enable the user to open additional windows to obtain additional information about a patient and to access

<img file="MX337609B_D0007.tif" />

üíViEÍJAD _ζ , V '1 ,,' S i TL1AL programmable setting menus. However, these new windows usually open on top of the vital statistics being displayed, obscuring the information in real time. What is needed is a central monitoring station that includes an additional, dedicated display. This dedicated screen would act as a workstation and would be responsible for presenting information for a single patient or for manipulating user defined settings.

In order to access and change settings, such as waveform amplitude and alarm thresholds, users of current central monitoring stations must access a separate window for each individual physiological parameter being measured and shown. The user spends additional time accessing each individual parameter and may be confused by the different interfaces of the different parameters, leading to decreased efficiency. Therefore, what is needed is a central monitoring station that provides the user with quick navigation to an interface where they can access settings for all measured parameters from a consistent screen view.

While current central monitoring stations allow the user a certain degree of flexibility with respect to τ Τ Τ '?! V ','.

What information to display, health care personnel would benefit from a higher level of personalization.

For example, a nurse might want to target a select group of patients who will require more care due to the severity of their respective conditions. Therefore, what is needed is a central monitoring station in which the space available on the display screens can be configured by the user based on the acuity of the patient. Monitoring personnel may also wish to view in real time vital statistics for only the most critical patients while data for the most stable patients may be omitted from the display screens. However, the healthcare provider will still want to be notified of an alarm condition occurring for a patient whose information is not presented at the central monitoring station, in addition to the audible alarm that sounds at the patient's bedside. Therefore, what is also needed is a central monitoring station that includes audible and visual alarms for patients for whom the display of continuous real-time vital statistics is unnecessary.

Additionally, current central alarm stations typically only notify health care personnel of active alarm conditions. If the provider of, - τ κ á 'and -ϊ% β .1 χνΧ τ · *' a 'feίί-ο' »'¹ ife.

ί ../ c. Cuidados ·· '··' care wants to examine trends over time, \ NU t, - ¿v_r ; -fe respecting the alarm activity for a specific patient, '' CJaT 'as frequency and type of alarm, he must access additional windows to obtain such a history. This again obscures portions of the display screens and requires additional time to search and analyze historical data. Therefore, what is needed is a central monitoring station that provides the user with a visualization of alarm activity for each patient over a certain period of time and also indicates the type, severity, and duration of each alarm.

Critical care settings can often have fast-paced periods of time in which hospital staff serve the needs of several critically ill patients all at once. Often caregivers can write that a patient is in surgery, has an afternoon consultation, or the time a medication was last administered. Typically, these notes are handwritten on sticky notes which are placed around the central monitoring station, with a tendency to disorderly fill the observation area. Therefore, what is needed is a central monitoring station that provides a more permanent record of quick notes and does so in a cleaner way.

DETAILED DESCRIPTION OF THE INVENTION

This specification is directed to a dynamic central monitoring station that includes multiple touch screens on which the displayed information is user configurable. The central monitoring station interfaces with bedside monitors and telemetry devices. The central monitoring station provides what is necessary for numerical and graphical presentation of vital patient statistics in real time on no less than two and up to four display screens. Real-time information for up to 48 patients can be displayed on the central monitoring station.

The central monitoring station described in this specification also enables the user to access the setting menus and view historical patient information. Monitored and collected physiological data include pulse oximetry (SpO₂), electrocardiography (ECG,), invasive blood pressure (IBP), non-invasive blood pressure (NIBP), electroencephalograph (EEG), body temperature, cardiac output, capnography (CO₂) ,

<img file="MX337609B_D0019.tif" />

respiration rates.

A dedicated display screen acts as a workstation and allows staff to view additional individual patient data, open setting menus, and gain quick access to the Intesys Client Suite (ICS) in which caregivers are able to view the data retrospective of the patient. The dedicated display screen enhances the user interface while allowing continuous presentation of vital statistics to all patients on the remaining display (s). The dedicated display screen provides what is needed for the integration of real-time and historical information. In one mode, up to 24 hours of data can be viewed within a 72-hour period at one time.

In addition, the user can remove a patient zone from the display screens if the bed representing the zone is not in use, resulting in an increase in the remaining zone areas. This enlarged area can be used for viewing additional patient data. Once the removed zone is reused, the user can restore the previous settings.

The central monitoring station described in this specification also includes an alarm surveillance zone. The alarm surveillance zone is a portion of the «SZU

continuous vital signs at the central monitoring station.

Rather, these patients do not appear on the display screens of the central monitoring station until, and unless an alarm situation arises, the time when a visual alarm appears on the screen and an audible alarm is sounded. This feature is user configurable and allows more screen space for observation of more critical patients.

In addition to traditional alarm notification, each patient under observation through the display screens of the central monitoring station has an alarm bar associated with their output reading. The alarm bar is a color-coded graphical representation of the alarm history for each patient, informing the caregiver of the frequency, duration, and type of alarm conditions experienced by each patient over a predetermined period of time. Pressing the alarm bar allows the caregiver to navigate the ICS alarm view where they can see each individual alarm occurrence. In addition to the alarm bar, they are displayed in existing services next to patient waveforms on display screens. Alarm messages inform

The central monitoring station also includes a quick navigation function to allow users easy access to system setting menus. The caregiver can press any icon of the physiological parameter to display a consistent parameter submenu window. From this window, the caregiver can press a tab for a specific parameter and then change the value settings for that parameter. A graphical representation of parameter values ​​over a predetermined period of time is included in the quick navigation window. This historical information helps the caregiver in setting minimum and maximum threshold values ​​for alarm notification. Also included, when applicable, is a waveform preview sub-window to provide the caregiver with an image of how the parameter waveform will appear before accepting changes.

Optionally, in one embodiment, the central monitoring station described in this specification provides a Replay function that allows clinicians to review the presentation of dynamic data, was

Recurrence provides a tool to retrospectively assess the reason (s) for clinical deterioration and serves as a quality mechanism to prevent similar instability for the corresponding patient and potentially other patients.

Optionally, in one embodiment, the central monitoring station includes electronic sticky notes that can be used to make notes regarding any information desired by the user for each patient. When a sticky note has been entered, a small sticky note icon next to the patient's name appears on the display screens. Pressing the sticky note icon displays a note window in which a caregiver can enter, view, or edit notes.

Optionally, in one embodiment, the central monitoring station includes a cardiac display that provides a cardiac view with specialized data presentation and enables users to quickly visualize pacemaker performance. Visualization

cardiac also provides a presentation of values ​​of

ST of specific guide combinations and an updated algorithm for telemetry. Cardiac visualization also provides a single trend as a general indicator that is used to alert a user to episodes of cardiac ischemia.

The system of the present invention is coupled to at least one screen, which displays information about the patient's parameters and the operation of the system, by means of a GUI. The GUI also features different menus that allow users to configure the settings according to their requirements. The system further comprises at least one processor (not shown) to control the operation of the entire system and its components. It should further be appreciated that said at least one processor is capable of processing programmatic instructions, and employs software comprising a plurality of programmatic instructions to carry out the processes described herein. In one embodiment, said at least one processor is a computing device capable of receiving, executing, and transmitting a plurality of programmatic instructions stored on a volatile or non-volatile computer readable medium.

In order to enable someone experienced in the field to practice the invention. The language used in this specification should not be construed as a disclaimer of any specific modality or used to limit claims beyond the meaning of the terms used in this document. The general principles defined in this document can be applied to other modalities and applications without departing from the spirit and scope of the invention. Also, the terminology and phraseology used is for the purpose of describing exemplary modalities and should not be considered limiting. Therefore, the present invention should be interpreted to the fullest extent encompassing numerous alternatives, modifications, and equivalents consistent with the disclosed principles and features. For the purpose of clarity, the details related to the technical material known in the technical fields related to the invention have not been described in detail so as not to unnecessarily obscure the present invention.

Room number 110 is positioned to the left of the display screen, in a reserved patient information area 115. Vital patient statistics, including both graphical waveform displays 125, numerical values ​​130, occupy the rest of screen area 120 on the right. Icons 135 with abbreviations for the different physiological parameters measured are also located in this display area 120.

Optionally, in one modality, an icon with a red X through it 140 notifies the caregiver that the displayed parameter is not currently being monitored for alarm notification.

Although only the information for only 4 patients is represented in Figure 1, the central monitoring station of the present invention has the ability, in one embodiment, to display vital signs for up to 48 patients. In one embodiment, a patient zone

145 It can be removed from the display screen if the corresponding patient bed is not in use. The remaining patient areas will therefore increase in size to fill the entire screen, allowing more data to be viewed for each patient. Conversely, as more patients are admitted to the unit, additional patient zones can be added to the display, in which case

<img file="MX337609B_D0025.tif" />

<img file="MX337609B_D0026.tif" />

In individual areas they will become progressively smaller. AND:

one modality, a plurality of patient zones are automatically added and displayed on each of a plurality of central monitoring stations whenever a new patient is added to the service, thereby causing the remaining patient zones to decrease in size of the display area up to a predefined pixel threshold within a range of 50-80 pixels, and preferably 62 pixels. In one embodiment, such a decrease is effected by decreasing the character, font, graphic, or icon size while maintaining substantially all of the information displayed. In another embodiment, such a decrease is effected by deleting certain information, such as graphs or physiological data, while substantially maintaining the size of the character, font, graph, or icon. In another embodiment, such a decrease is effected by deleting certain information, such as graphs or physiological data, while partially maintaining the size of the character, font, graph, or icon.

In one mode, when a new patient occupies a previously empty bed, the system will automatically detect a living being and the central monitoring station will automatically fill a patient area on the display screen. A caregiver can then admit the patient from the central monitoring station.

<img file="MX337609B_D0027.tif" />

Furthermore, in one embodiment, the central monitoring station of the present invention allows dynamic display configuration depending on the acuity of the patient. The acuity of the patient is determined by the system that examines a number of parameters which can be

Dedicated, the remaining displays continue jSf'élssent real-time vital statistics for all patients. Having a dedicated display allows the caregiver to work on one patient while not sacrificing any necessary screen space for continuous monitoring of the other patients. The dedicated visualization works as a separate workstation providing the user with quick access to view ICS retrospective data.

Referring to Figure 2, patient name 205 and room number 210 are presented in the upper left corner of the dedicated display screen. Under this information, in one modality, there are four tabs that include the Header View 215, Trends 220, Calculations

225, and Patient Information 230. Pressing one of these tabs provides the caregiver with historical information and additional options related to the patient's vital signs. For example, in a modality, the tab of the

Header View 215 provides additional buttons that allow the user to save a baseline 216, show / hide baseline 217, print 218, and display an electronic sticky note 219.

The portion Remaining bottom of non-dedicated display screen 310 is now used as a workstation and focused on a patient. Although the information for the other patients has been displayed in a smaller screen area, it is still visible to the caregiver. Therefore, a caregiver can use a non-dedicated display as a workstation without losing visibility of the remaining patients.

A non-dedicated display can be used as a workstation whenever a dedicated display is not available, for example, when a dedicated display is not present on the central monitoring station or when the dedicated display is in use by another caregiver.

Typically, these are less critical patients for whom continuous monitoring of vital signs is unnecessary. Alarm surveillance zone 405 provides a means of notifying caregivers of alarm conditions for these patients without relying on the alarm notification present at the bedside. A caregiver can remain at the central monitoring station to observe the condition of the most critically ill patients and be assured that they will be notified if a less critically ill patient enters an alarm state. In one mode, the alarm monitoring zone can display alarm states for up to 8 patients. In one mode, an alarm message appears in the alarm monitoring zone during an alarm state.

In one embodiment, the color of the alarm message text means the severity of the alarm state. For example, red text means a severe alarm condition, yellow text means a moderate alarm condition, and blue text means a device disconnection or malfunction. In a

mode, the alarm message flashes. In a modali an audible alarm occurs at the central monitoring station in addition to the alarm message.

FIG. 5 is a graphical user interface of one embodiment of a central monitoring station display screen depicting alarm bar 505 and persistent alarm messages 510. In one embodiment, alarm bar 505 is positioned at the upper right corner of the patient information area. Alarm bar 505 informs the caregiver of the patient's alarm status over a predetermined user-defined period of time. In one mode, the alarm bar means the patient's alarm status for the past 30 minutes. The color of the bar signifies the severity of the alarm and the length of each colored segment within the bar signifies the duration of the alarm. In one mode, red on the alarm bar means a severe alarm state, yellow means a moderate alarm state, and blue means disconnection or malfunction of the device. In one modality, for example, a large yellow segment on the alarm bar notifies the caregiver that the patient was in a moderate alarm state for several minutes.

Press the alarm bar for a patient user to the ICS alarm view. The Figure is a screen capture of a modality of a central monitoring station display screen representing the ICS alarm view. In this mode, the ICS 605 alarm view occupies the bottom two-thirds of the display while the top third fills with patient zones 610. The ICS alarm view provides the caregiver with historical data regarding the alarm states experienced by a specific patient.

Based on these data, the caregiver can adapt the therapy or change the alarm threshold limits.

As is commonly known, patients in critical care settings often have precipitous changes in physiology. In such cases, sometimes the moving waveforms and numerical data presented in a display matter of the central monitoring station can be lost by a clinician. However, at the time of detrimental changes in vital signs, she refers the clinician to respond immediately to the patient's abnormal physiology. The present invention provides a Replay function that enables clinicians to perform dynamic data presentation as seen on a bedside display just before physiological change 'F i · w (pre-event), during physiological change (eÍ « 'éypntoÓ;) after the patient has stabilized (post-event) .. ^

Therefore, the Repeat function provides a tool to retrospectively assess the reason (s) for clinical deterioration and serves as a quality mechanism to prevent similar instability for the corresponding patient and potentially other patients. Additionally, the Replay feature can be used by clinicians in any intensive care unit, emergency department, or operating room to assess the sequence of clinical events leading to an unstable clinical condition. The Replay function can serve as a communication tool between nurse and doctor and other health care workers and can also be used in staff training.

FIG. 6A is a screen capture of one embodiment of a central monitoring station display screen depicting a Replay of a selected item of an alarm history event 615, in accordance with an embodiment of the present invention.

Referring again to Figure 5, the central monitoring station display screen also notifies the caregiver of the latest type of alarm through an alarm message 510 displayed next to the patient's waveforms. In one embodiment, the text of the alarm message 510 is color coded to signify the severity of the alarm. In one embodiment, the text of alarm message 510 is white and is highlighted with a specific color to represent the severity of the alarm

For example, in one mode, red indicates a severe alarm state, yellow indicates a moderate alarm state, and blue indicates disconnection or malfunction of the device. The alarm message is persistent and will remain on the display screen until recognized by a caregiver. In one mode, the caregiver can acknowledge the alarm message by pressing it.

The central monitoring station includes a^! Quick navigation to allow üsüár Íóé '' '' áCC'etteT easily to system settings menus. Figure 7 is a graphical user interface of one embodiment of a central monitoring station display screen with a popup window 705 representing the parameter setting screen of the quick navigation function.

When a caregiver presses any parameter icon, the quick navigation feature displays the settings menu containing buttons for all the parameters measured for that patient. By pressing a parameter button, the caregiver can change the settings for that particular parameter.

For example, in one mode, a caregiver may choose to change the settings for ECG, SpC> 2, RESP, NIBP, TEMP, and, press ART and PA from the same settings menu by pressing the appropriate parameter button. This enables the caregiver to adjust all parameters from a consistent view without having to exit and re-enter separate setting menus, thereby increasing care efficiency.

As known in the art, measurement of a ST segment of the ECG is a standard technique for detecting cardiac ischemia. A trained clinician can check the level of change on different ECG guides that indicate which region of the heart is being deprived of oxygenated blood.

Many patients may have silent ischemia, in which

<img file="MX337609B_D0036.tif" />

which the patient does not feel discomfort despite minor transient ischemic attacks that are common precursors of a potentially fatal myocardial violation. Therefore, continuous monitoring of ST segment levels is common practice in many hospital care areas.

However, seeing the ST segment level changes (from baseline) in multiple guides can be confusing for an inexperienced user. Also, a typical patient monitor may have limited screen space on which to display all available ST data guides (up to 12). The present disclosure provides a single trend as a general indicator which is used to alert a user to episodes of cardiac ischemia.

Figure 13 is a graphical user interface of one embodiment of a central monitor station display screen depicting the cardiac view window. Cardiac view provides specialized data presentation, which the caregiver can quickly visualize pacemaker performance. In one embodiment, the cardiac view window provides an ST index that includes a presentation of ST values ​​for specific guide combinations. The ST index is a sum of ST values ​​measured every second and can be predefined or set

DUSTRJAl by the user. ST values ​​are measured as a specialized ST software package. The measured values ​​are displayed graphically and the alarm thresholds can be set by the user. The ST index can also be used to quantify areas of the heart that are damaged. Figure 13 depicts a real-time ST trend graph 1305 and a pacemaker heartbeat graph 1310.

In one modality, the ST segment levels for the 3 most orthogonal guides available are combined into a single global ischemic index (Gil) using the following equation:

Gil = | ΔΧ | +) ΔΥ | + | ΔΖ | (EQUATION 1), where X, Y, and Z are three semi-orthogonal ECG guides, and the deltas are deviations from the learned baseline for each guide.

Because Gil incorporates ST follow-up data from orthogonal guides, ischemia in any portion of the heart will appear in Gil's trend. If an ischemic episode is visible in Gil's tendency, then the clinician can be alerted to the episode and appropriate diagnostic steps can be taken to identify exactly

which guides, and by inference, which parts of the ^ are showing signs of ischemia. Figure 13A illustrates a global ischemic index showing an ischemic episode, in accordance with an embodiment of the present invention. The trend shown for the Gil level as illustrated in Figure 13A appears as a red line 1315 during ischemic episodes and a green line 1320 otherwise.

In one embodiment, the central monitoring station of the present invention also includes an updated algorithm with the cardiac view. The updated algorithm has additional arrhythmia capabilities and expanded ST functions with indexes. New measurement capabilities are also included, including QRS duration, QT and QTc measurement, and extended PR intervals. Additionally, the updated algorithm provides what is needed for rhythm-related detection and reporting for atrial fibrillation (Afib), bradycardia, tachycardia, Ideoventricular rhythm (IVR), and Accelerated Ideoventricular rhythm (AIVR)

Rhythm).
