ALARMS

Description of Alarms

The NPB-290 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.

Refer to the “Management of the Loss-of-Pulse Alarm”

paragraph later in this section for a detailed description of the

loss-of-pulse alarm.

2. Medium-priority alarm: Indicated by a medium-rate,

medium-pitched, pulsing tone. A medium-priority alarm

sounds when any measured patient parameter (%SpO

2 or

Pulse Rate) moves outside the set alarm limits.

During a medium-priority alarm, the yellow display turns red

and flashes with the patient parameter that violated the limit

(%SpO

2 or Pulse Rate).

3. Low-priority alarm: Indicated by a slow-rate, low-pitched,

pulsing tone. A low-priority alarm sounds during the

following conditions:

• low battery (while operating on battery power)

• when an SpO

2 cable has disconnected

• monitor failure

• 50 seconds after loss of pulse is detected in the

presence of continuous motion

• During a low battery alarm, the Low Battery

indicator illuminates and the alarm tone sounds

immediately, even if the alarms are silenced or set to

OFF.
