Alarms and Limits

Alarm Summary 

The Model 7500FO detects both patient and equipment alarms. In general, patient alarms are 
identified as high priority, while equipment alarms are identified as medium priority. High priority 
alarms always take priority over medium priority alarms. Alarm indicators remain active for as long 
as the alarm condition is present.

Patient Alarms

If patient SpO

2

 or pulse readings are equal to or above the upper alarm limit, or if they are equal 

to or below the lower alarm limit, the device will signal a high priority alarm, indicated by numeric 
LEDs flashing in sync with the red Alarm Bar LED.

Visual Indicator

Low Battery Alarm

Battery LED blinks in sync with Alarm Bar LED. This alarm 
signifies that the battery has less than 30 minutes of normal 
operation. When Critical Low Battery is reached, the device’s 
oximetry functions are disabled.
