High Priority Alarms

High priority alarms require immediate attention to the patient. High priority alarms are indicated
with rapidly blinking red LEDs in sync with the Main Alarm LED, when alarm limits are met or
exceeded. Low perfusion is indicated by a red segment on the Pulse Strength Bar Graph LED.
High priority alarms are: 3 beeps, pause, 2 beeps and a 10-second pause. This sequence
repeats until the alarm is cleared or silenced. The following table describes the default settings,
adjustment ranges and intervals.
