High Oxygen Flow
This is a high priority alarm. It occurs when the concentration of
oxygen from the device is 10% above the FiO
2
set point for more than
30 seconds. This could be caused by a problem with the output of the
oxygen source.
Low Oxygen Flow
This is a high priority alarm. It occurs when the concentration of
oxygen from the device is 10% below the FiO
2
set point for more
than 30 seconds. This could be caused by the oxygen source being
disconnected from the device, an occlusion in the tubing from the
oxygen source to the device, or a problem with the output of the
oxygen source.
High Oxygen Inlet Pressure
This is a high priority alarm. It occurs when the pressure of the
oxygen from the source measures greater than 87 psi.
Low Oxygen Inlet Pressure
This is a high priority alarm. It occurs when the pressure of the
oxygen from the oxygen source measures less than 40 psi. This could
be caused by the oxygen source being disconnected from the device,
an occlusion in the tubing from the oxygen source to the device, or a
problem with the output of the oxygen source.
Circuit Disconnect Alarm
This is a high priority alarm. It occurs when the breathing circuit is
disconnected or has a large leak. The device continues to operate.
The alarm will automatically terminate when the leak is fixed for
6 seconds and breaths are delivered again.
WARNING
You should not rely on any
single alarm to detect a circuit
disconnect condition. The Low
Tidal Volume, Low Minute
Ventilation, Low Respiratory
Rate, and Apnea alarms should
be used in conjunction with
the Circuit Disconnect alarm.
The Apnea alarm is only
intended for spontaneously
breathing patients.
