2 Chapter 1 General information Welch Allyn Acuity Central Monitoring System

Acuity System software further processes data acquired from patient monitors. Acuity Systems with the Arrhythmia Analysis module calculate heart rate using multiple ECG leads and arrhythmia analysis algorithms.

The Acuity System is not directly connected to patients. It is designed to be used as a central monitoring system for a set of patient monitors that support both continuously and intermittently acquired data. Supported monitors include, but are not limited to, the following Welch Allyn devices: Propaq Welch Allyn 1500 Patient Monitor®, as configured to interface with the Acuity System.

The Acuity System and distributed monitoring devices are prescription devices to be used by authorized health care professionals using standard institutional procedures and standards of care for patient monitoring. Staff training in the operation of the Acuity System and the patient monitoring devices connected to it is essential for optimal use. Users should be skilled at the level of a technician, nurse, physician, health care provider or medical specialist, with the knowledge and experience to acquire and interpret patients’ vital-signs data.

Individuals using the Acuity System should be familiar with its operation as described in this manual, and they should understand all warnings and cautions in the manual.

General warnings and cautions

Warnings

Related to system components and configuration

WARNING Use only accessories approved by Welch Allyn. The use of any other accessories can result in inaccurate patient data, can damage the equipment, and can void your product warranty. See the accessory list or visit

www.welchallyn.com.

WARNING Always use accessories according to the standards of your facility and according to the manufacturer's directions.

WARNING Welch Allyn has verified that Welch Allyn-specified network requirements for this Acuity System have been met. Altering the cabling or connecting the Acuity System to another type of power source could damage the equipment, cause system restarts or hazardous conditions on the network, or result in inaccurate patient information at the Acuity Central Station.

WARNING Do not change Acuity System components or configuration, such as removing or adding a printer or substituting hardware, without approval by Welch Allyn. Such changes could degrade system performance and affect patient monitoring.

WARNING Devices connected to the Acuity System must be certified for overall system compliance according to the European Norm 60601-1 and 60950 safety standards. The interconnection of any device with an Acuity System must comply with IEC 60601-1-1. Devices listed in the Acuity System installation planning guide comply with these standards. If in doubt about network connectors or devices, please consult your facility’s Biomedical Engineering department or Welch Allyn Technical Support.

WARNING It is strongly recommended that Acuity Systems be installed with continuous power sources and redundant means of operator surveillance, such as secondary central stations and hallway message panels. Acuity System alarms, alerts or other events can go unnoticed if clinical personnel are not present at the Acuity Central Station or if interruptions occur in power or system operations. You are responsible to provide percent reliable power to the central station. The central station will only work with reliable AC power.

WARNING Ensure that no headphones or headphone adapters are connected to the headphone input of your computer. A connection in the headphone jack of a computer will cancel speaker output for any audible alarms associated with the Acuity System.

4 Chapter 1 General information Welch Allyn Acuity Central Monitoring System

WARNING Ensure that the volume level on your computer is not set too low or is not set to mute as this may cause you to miss audible alarms generated from the Acuity System.

WARNING Replace central station hardware within the the lesser of 3 years or the original equipment manufacturer’s specification. Failure to perform preventative maintenance can impact system performance and availability.

WARNING The bedside patient monitor is the primary alarming source for the patient, and the central station is a backup alarm source. The central station is only as reliable as its network and should be relied on only as a backup alarming device.

WARNING Lethal arrhythmia (LTA) analysis by the central station is only as reliable as the connection to the bedside monitor. With the exception of the Welch Allyn 1500 monitor in a disconnected state, which provides its own LTA analysis and alarm, the central station is the primary source for LTA analysis. LTA alarms will occur at the central station and will also be communicated to the bedside monitor for annunciation. Thus, in a central station workflow, LTA analysis and alarming will only be as reliable as the network.

WARNING A paired system CPU (high-availability pair) is strongly recommended to provide system redundancy.

WARNING The electronic medical record system (EMR) is not intended to serve as a primary monitoring system for alarms or as an exclusive source for patient data in determining patient care. The Acuity System is capable of transferring historical patient data to most customer-specified EMR systems through the Welch Allyn Connectivity Server (WACS). However, the transferred patient data is not a substitute for the patient data collected by the primary monitoring system.

Related to close physical surveillance and specific patient populations

WARNING It is important that clinicians understand and communicate to all staff using the Acuity Central Station that any arrhythmia analysis software program is an effective tool to assist in patient care, but arrhythmia analysis packages are unable to achieve 100 percent accuracy for all morphologies and occurrences of QRS and PVC detection. Thus, close physical surveillance and clinical interpretation of cardiac data must still be an integral part of every patient’s care. Clinicians must review all data obtained from the Acuity System before implementing therapy based on the data.

WARNING Ensure that Acuity System patients are kept under close surveillance, especially patients prone to arrhythmia events. Use the Acuity System only in conjunction with close surveillance by trained clinicians.

Directions for use Chapter 1 General information 5

WARNING Do not use the Arrhythmia Analysis or ST Analysis feature on neonates. The Arrhythmia Analysis and ST Analysis options are not intended for use with neonatal patients.

WARNING Keep all pacemaker patients under close observation. Rate meters might continue to count the pacemaker rate during occurrences of cardiac arrest or some arrhythmias. Do not rely solely upon rate meter alarms.

WARNING Central station alarms and other events can go unnoticed if clinical personnel are not present at the central station or if interruptions occur in power or system operations.

WARNING The leading cause of patient death or serious injury reported with the use of patient monitoring equipment is failure to respond to alarms notifying the user of an adverse change in patient condition. If you are relying on visual alarm notifications, maintain a clear line of sight and remain within 4 meters of the central station. If you are relying on audio alarm notifications, make sure that you can hear audio alarms from where you are. Set the volume as needed considering the environment and ambient noise levels. Verify that the alarm is audible to a clinician working at the maximum distance from the central station.

Related to monitoring interruption

WARNING If you view an Acuity System display remotely and its primary Acuity System fails, you lose all access to the remote display. Monitoring a patient at an Auto-Open Secondary (AOS) or Patient List Review (PLR) remote station is not a substitute for monitoring a patient at the primary Acuity Central Station.

WARNING Use wireless monitors only on patients who can tolerate intermittent monitoring interruptions. All wireless systems are prone to intermittent signal dropout. During signal dropout periods, arrhythmia and STsegment analyses cannot be performed, and the Acuity System does not show alarms or alerts.

WARNING If an Acuity Central Station display is intentionally or inadvertently muted, alarm and alert tones do not occur at the display. If your central station display includes audible tones, remain aware of whether they are occurring. If they appear to have stopped, ensure that tones are restored.

WARNING If normal central processing unit (CPU) operation is interrupted, for example, during CPU maintenance, scheduled and unscheduled reboots, power loss or a high-availability (HA) CPU switchover period, central station monitoring and analysis temporarily stop.

The Acuity System cannot collect patient review data during the interruption period. That data becomes permanently unavailable.

Auto-reboots and HA CPU switchovers occur infrequently, but poor environmental conditions and failure to perform preventative maintenance can increase frequency of occurrence.

6 Chapter 1 General information Welch Allyn Acuity Central Monitoring System

WARNING Whenever an interruption in Acuity System CPU operation occurs, please contact Welch Allyn Technical Service soon to ensure that your entire system has returned to normal operating condition and that it does not require further service.

WARNING Auto-reboots can occur during internal software checks, and wireless connection can be occasionally disrupted. During this period, the bedside monitors continue to provide their primary alarming functions.

Cautions

Caution U. S. Federal law restricts this device to sale by or on the order of a physician.

When you disconnect from a remote viewing session, the windows and views are not reset. It is recommended that you close all patient windows on the viewing client before disconnecting.

Directions for use Chapter 2 Acuity System overview 15

Paired system CPUs (High-availability pairs) and switchovers

Acuity Systems that typically support at least 29 patients include a high availability (HA) central processing unit (CPU). The HA CPU is a redundant Acuity System CPU.

An HA CPU assumes control if the Acuity System CPU’s operation is interrupted. An HA CPU “switchover” occurs to ensure minimal loss of Acuity Central Station monitoring capability. Historical data that had been gathered by the non-operational CPU before the switchover might not be available for some patients until that CPU becomes operational.

At any one time, displays in a paired CPU system should all receive input from either the Acuity System CPU or the HA CPU.

To ensure that all displays in a paired CPU system receive input from the same CPU

System buttons

The system buttons in the lower left corner of the Acuity Central Station screen provide quick access to frequently used system-wide functions.

The Patient List button opens the Patient List window, which enables you to preadmit, readmit, transfer, and discharge patients in your Acuity System. You can also view and print stored waveforms and trends of patients who have not been monitored by the Acuity System for (up to) 96 hours.

If your Acuity System is connected within a network of Acuity Systems, depending upon the type of network, you can perform the above functions for networked patients. You can also locate networked patients, edit their patient information, change their alarm limits and suspend their alarms and alerts.

A Patient List button is displayed also in review windows that have been opened by way of the Patient List window.

When you click and hold the View Wireless button, the map icons of all patients that are connected to wireless monitors change to Wireless icons; other patient icons become gray boxes. The map returns to normal when you release the button on your mouse or trackball.

The System Administration button opens a window that allows designated system administrators to create new user identifications and to adjust system time.

The Sort Windows button sorts all Waveform Windows and any open Virtual Monitor windows by room number, in alphanumeric order. The sorting only applies to the current screen view.

• Waveform Windows for monitors without confirmed patient IDs are located at the end.

• For networked Acuity Systems with more than one Acuity System unit, rooms are grouped together according to Acuity System unit.

• The order in which windows are displayed depends on how your system has been configured. Generally, windows are displayed from top to bottom and left to right.

If the Sort Windows button is grayed-out, your system is not configured to sort windows. In this case, each Waveform Window space is assigned to a particular room, and unassigned wireless monitors occupy unoccupied Waveform Window spaces. Wireless monitors are “bumped out” to different unoccupied spaces if their spaces become occupied by hardwired monitors.

When a preadmitted patient arrives:

• If the patient is connected to a wireless monitor, at the patient monitor you can simply confirm the patient ID and add a room number.

• If the patient is connected to a hardwired monitor, you can go to the Acuity Central Station and confirm the patient by entering only the ID number.

If a patient is already monitored by a networked Acuity System, a duplicate entry is not allowed, because patient information could be lost.
