System Alarms - Philips RESPIRONICS Trilogy Mode D'emploi

High Inspiratory Pressure Alarm
This alarm occurs in several stages and escalates from an audible beep for the first two occurrences to a high priority
alarm if the problem continues. It is detected differently for volume and pressure therapy modes.
For volume modes, the alarm will sound if the measured patient pressure exceeds the High Inspiratory Pressure setting
specified by the clinician. The alarm will automatically terminate when the peak inspiratory pressure is less than or equal to
the High Inspiratory Pressure alarm setting.
For pressure modes, the alarm occurs when the delivered pressure exceeds the target patient pressure by 5 cm H O or
2
more during the inspiratory phase. The device will automatically cycle to the expiratory phase and continue to operate. The
alarm will automatically terminate when the delivered pressure falls within 5 cm H O of the target patient pressure during
2
the inspiratory phase.
Low Inspiratory Pressure Alarm
This is a high priority alarm. It is detected differently for volume and pressure therapy modes.
For volume modes, the alarm will sound if the measured patient pressure is less than the Low Inspiratory Pressure setting
specified by the clinician. The alarm will automatically terminate when the peak pressure at the end of the breath is greater
than or equal to the Low Inspiratory Pressure alarm setting.
For pressure modes, the alarm occurs when the delivered pressure is 5 cm H O or more below the target patient pressure
2
during the inspiratory phase. The alarm will automatically terminate when the delivered pressure comes within 5 cm H O
2
of the target patient pressure during the inspiratory phase.
High Minute Ventilation Alarm
This alarm is a high priority alarm. It occurs when the patient's minute ventilation is greater than the High Minute
Ventilation alarm setting. The device continues to operate. The alarm will automatically terminate when the calculated
minute ventilation is less than the High Minute Ventilation alarm setting.
Low Minute Ventilation Alarm
This alarm is a high priority alarm. It occurs when the patient's minute ventilation is less than the Low Minute Ventilation
alarm setting. The device continues to operate. The alarm will automatically terminate when the calculated minute
ventilation is greater than the Low Minute Ventilation alarm setting.

System Alarms

Loss of Power Alarm
This is a technical alarm condition that is treated as a high priority alarm. It may occur when a complete power failure has
occurred and power was lost while the device was providing therapy. This may happen if the internal battery was the only
power source in use and was completely depleted.
Ventilator Inoperative Alarm
This is a technical alarm condition that is treated as a high priority alarm. It occurs when the ventilator detects an internal error
or a condition that may affect therapy. The device will shut down if the cause of the failure indicates that the device cannot deliver
therapy safely. If the device can deliver therapy at a limited level, the device will continue to deliver limited therapy.
