ALARMS
The following paragraphs describe the three levels of audio
alarms and discuss the management of the loss-of-pulse alarm.
Description of Alarms
The W-395 has three levels of audible alarms.
1. High-priority alarm: Indicated by a fast-rate, high-pitched,
pulsing tone.
A high-priority alarm sounds after loss-of-
pulse is detected.
During a high-priority alarm, the display flashes with the
patient parameter that violated the limit.
2. Medium-priority alarm: Indicated by a medium-rate,
medium-pitched, pulsing tone.
A medium-priority alann
sounds
when any measured patient parameter moves outside
the set alann limits, and, if enabled, the SatSeconds limit
has been exceeded.
During a medium-priority alarm, the display flashes with the
patient parameter that violated the limit
(%Sp02 or Pulse
Rate). If the alarm is a
SatSeconds alarm, the SatSeconds
indicator will be full.
3.
Low-priority alarm: Indicated by a slow, low-pitched,
pulsing tone.
A low-priority alann sounds during the
following conditions:
low battery (while operating on battery power)
when an SpOz cable or sensor has been disconnected
from the monitor or a patient
monitor failure
When operating on
DC power, during a low batteiy condition,
the Low Battery Indicator illuminates and the alarm tone sounds
immediately, even if the alarms are silenced or set to OFF.
