Apnea Alarm; High Vte Alarm; Low Vte Alarm; High Vti Alarm - PHILIPS Respironics Trilogy 100 Clinical Manual

Apnea Alarm

This is a high priority alarm. It occurs when the patient has not
triggered a breath within the time specified in the apnea alarm
setting. The device continues to operate. The alarm will automatically
terminate when two consecutive patient breaths are detected that
meet the apnea alarm time setting.

High Vte Alarm

This is a high priority alarm. It occurs when the estimated exhaled
tidal volume is greater than the High Vte alarm setting for three
consecutive breaths. The device continues to operate. The alarm will
automatically terminate when a breath occurs in which the exhaled
tidal volume does not reach the High Vte alarm setting.

Low Vte Alarm

This is a high priority alarm. It occurs when the estimated exhaled
tidal volume is lower than the Low Vte alarm setting for three
consecutive breaths. The device continues to operate. The alarm will
automatically terminate when a breath occurs in which the exhaled
tidal volume exceeds the Low Vte alarm setting.
When AVAPS is on, this alarm will occur when the calculated tidal
volume is less than 90% of the target tidal volume setting. The alarm
will automatically terminate when a breath occurs in which the
exhaled tidal volume is equal or greater to 90% of the target tidal
volume setting.

High Vti Alarm

This is a high priority alarm. It occurs when the delivered tidal
volume is greater than the High Vti alarm setting for three
consecutive breaths. The device continues to operate. The alarm will
automatically terminate when a breath occurs in which the delivered
tidal volume does not reach the High Vti alarm setting.
Note: Apnea alarm is not
available in T and CV modes.
