Handheld pulse oximeter user’s manual
Chapter 4 Alarm
’Alarm’ refers to a prompt that is given by the oximeter
through visual, audible and other means, to alert medical
personnel when a vital sign appears abnormal or the
oximeter experiences a technical problem.
Note: The oximeter generates all audible and visual
alarms through a speaker, a visual alarm lamp
and the screen.
4.1 Alarm Categories
The oximeter’s alarms fall into three categories:
1.Physiological alarms
Physiological alarms are triggered when a monitored
parameter moves outside of set alarm limits, or by an
abnormal patient condition. Physiological alarm messages
are displayed in the physiological alarm area.
2.Technical alarms
