WARNING!
Under certain conditions, such as small prongs and high respiratory rates, the Circuit Disconnect Alarm may
not recognize that the prongs have been dislodged from the nares. Ensure proper physiologic monitoring is
used.
High nCPAP pressure
A high priority audible/visual alarm will be activated whenever the nCPAP exceeds the high airway pressure threshold for
a period greater than 15 seconds.
Threshold: Set CPAP Level + 3 cmH

Tolerance: ± 0.5 cmH

Note:
Threshold is automatically updated upon acceptance of a change in the nCPAP control setting.
Low nCPAP Pressure
A high priority audible/visual alarm will be activated whenever the nCPAP pressure falls below the low airway pressure
threshold for a period greater than 15 seconds.
Threshold: Set CPAP Level - 2 cmH

Note:
Threshold is automatically updated upon acceptance of a change in the nCPAP control setting.
nCPAP Pressure Limit
A high priority audible/visual alarm will be activated whenever the nCPAP pressure is greater than airway pressure limit
for 3 seconds. The alarm will deactivate when the nCPAP pressure drops below 4.5 cmH
