Alarm System (CPAP)
The Pulse Oximeter has a separate alarm system explained in the
Alarm
System (Pulse Oximeter)
section.
The CPAP alarm system will generate visual and audible alarm signals to notify you of
alarm conditions that the system detects.
2. Alarm Indication
Audible alarms may be suspended, while visual alarms may not. The alarm silence
button is used to temporarily silence audible alarms for 110 seconds. When this
button is pressed, a yellow light is illuminated next to the button and audible alarms
are silenced. When the button is pressed and the yellow light is already on, the yellow
light turns off and alarm sounds are restored.

is an alarm signalling on the display, address the alarm using the

display, disconnect the patient from the breathing circuit and occlude the patient
interface with your palm (covered in a sterile glove). If bubbling resumes, check
patient for apnea or air leakage from the mouth. If bubbling does not resume, there
is likely a leak in the breathing circuit.
