Directions for use
Related to monitoring interruption
Cautions
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 ST-
segment 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.
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.
Caution U. S. Federal law restricts this device to sale by or on the order of a
physician.
