Philips RESPIRONICS Trilogy Mode D'emploi page 3

High Expiratory Pressure Alarm
This is a high priority alarm. It occurs when the delivered pressure exceeds the target patient pressure during the
expiratory phase by 5 cm H
continues to operate. The alarm will automatically terminate when the delivered pressure comes within 5 cm H
target patient pressure during the expiratory phase.
Low Expiratory Pressure Alarm
This is a high priority alarm. It occurs when the delivered pressure is 5 cm H
during the expiratory phase. The device continues to operate. The alarm will automatically terminate when the delivered
pressure comes within 5 cm H
High Oxygen Flow
This is a high priority alarm. It occurs when the concentration of oxygen from the device is 10% above the FiO
for more than 30 seconds. This could be caused by a problem with the output of the oxygen source.
Note: Trilogy202 only.
Low Oxygen Flow
This is a high priority alarm. It occurs when the concentration of oxygen from the device is 10% below the FiO
for more than 30 seconds. This could be cause 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.
Note: FiO settings of less than 31% result in a Low Oxygen Flow alarm limit corresponding to the amount of oxygen in ambient
2
air (21%). This may cause the alarm to not be generated if oxygen is no longer supplied. An external oxygen monitor to verify the
oxygen concentration in the delivered gas is recommended in this instance.
Note: Trilogy202 only.
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.
Note: Trilogy202 only.
Low Oxygen Inlet Pressure
This is a high priority alarm. It occurs when the oxygen source inlet pressure 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 oxygen source supply system.
Note: Trilogy202 only.
Circuit Disconnect Alarm
This is a high priority alarm. It occurs when the breathing circuit is disconnected, has a large leak, or if the patient airway
is completely occluded. The device will continue to operate. This alarm will automatically terminate when the circuit is
reconnected, the leak is fixed, or when the occlusion in the airway is removed.
