Chapter 7 Alarms and Indicators
675–101–101 Rev. P
Alarm Types
The following alarm systems are provided with the Infant Flow
SiPAP driver.
Electronic alarms are set after 2 minutes of operation without operator intervention
although the operator can manually set or reset them if required. Refer to Appendix
C for information on troubleshooting alarms.
Supply Gases Failure
If the differential pressure between the two inlet gases falls outside of the limit of
30 PSI (2.0 bar) or one gas fails completely, an alarm will sound and the gas at the
higher pressure only will be delivered to the patient.
High Airway Pressure
A HIGH priority audible and visual high pressure alarm activates when pressure
reaches 3 cmH
2
O above the measured airway pressure.
Airway Over-Pressure Limit Alarm
A HIGH priority audible and visual high pressure alarm activates at 11 cmH
2
O during
NCAP and time triggered BiPhasic modes and 15 cmH
2
O in BiPhasic tr mode. Upon
activation of this alarm, the patient circuit pressure drops to near zero. Pressure is
restored after 3 seconds, and reduces to near zero again should the condition
causing the alarm remain.
Low Airway Pressure
A HIGH priority audible and visual low pressure alarm activates if pressures fall to
2 cmH
2
O below the measured airway pressure or at 1.5 cmH
2
O, if this would
otherwise be less than zero.
High and Low % O
2
HIGH priority audible and visual alarms are provided at ± 5% of the measured FiO
2
with an upper maximum limit of 104% and a lower minimum limit of 18%.
A low hazard warning occurs at 18% Oxygen or below.
Low Battery Charge
If the battery charge falls below 40% the battery charge indicator changes from
green to red as a warning indicator. In this instance, plug the driver into an approved
AC power source.
Low Battery Voltage
If the battery voltage falls to < 11.10 V for 5 seconds a MEDIUM priority audible and
visual alarm is activated. In this instance, plug the driver into an approved AC power
source.
