Q. What triggers the SiPAP nCPAP driver to alarm?
A. Refer to the operator manual for the list of alarm
triggers. Some of the more common alarms are:
• The alarms were not reset after a change in CPAP
level or oxygen setting. To x, hold the alarm reset
bar down for three seconds to reset the alarm
thresholds.
• Check the system for leaks. The nasal interface may
be improperly positioned or the infant’s mouth may
be open.
Q. Why does the SiPAP not deliver a pressure boost when
the manual breath button is pressed?
A. When the system is in the CPAP mode, the high
flowmeter needs to be set for the manual breath to
be active.
Q. Why is the system not reaching the high pressure
setting? The SiPAP system is set at 10 cmH
2
O/5 cmH
2
O,
T-high 0.3 sec, Rate 20, 30%. Even when the flow rate
on the high pressure flowmeter was increased, the
maximum high CPAP reached was 9 cmH
2
O.
A. The SiPAP system has a slow ramp to the high pressure
setting. If the inspiratory time is not long enough, the
high pressure is not reached. First, check the breathing
circuit and generator assembly for leaks. If the problem
does not correct, increase the T-high setting, monitor
for an increase in the high pressure and increase the
T-high until the desired pressure is reached.

Q. Can the SiPAP nCPAP driver deliver nitric oxide?
A. The FDA has approved the use of the INOMAX
DS with the SiPAP driver for delivering nitric oxide.
Refer to the Ikaria INOMax operator manual for the
directions of use.
Q. When the system is connected to the infant,
a flow rate of 9 LPM does not deliver 5 cmH
2
O.
Why is this?
• A leak is in the breathing circuit and
generator assembly.
• The prongs and mask interfaces are not the
proper size.
• The strap tension is too tight, which can break
the seal on the interface.
• Leaks in the circuit could be caused by loose
connections, pinholes or temperature probes
not fully inserted in the temperature port.
Q. Air is backing up into the humidifier’s water auto-feed
system. What should I do?
A. Ensure the height of the water bag is at least 50 cm
above the humidifier chamber. If air still accumulates,
apply a pressure cuff around the water bag.
