Alarm limits
CAUTION: TO ENSURE THAT ALARM LIMITS ARE APPROPRIATE FOR THE PATIENT
BEING MONITORED, CHECK THE LIMITS EACH TIME THE RAD-8 IS USED.
When an alarm limit is exceeded, an audible alarm activates and the Alarm Bell
flashes red
for high priority alarms.
When a sensor is not connected to a patient, “SEN OFF” message
will show on the display. When a sensor is not connected to its cable, “NO SEN” message
will show on the display.
NOTE: An audible alarm will accompany the visual indicators unless the Rad-8 has been
set to
Interface Alarms "Off" (only SpO
2
and BPM alarms muted) or to Sleep
Mode (all alarms muted).
