Circuit Disconnect (MPV) Alarm
This is a high priority alarm. It occurs when a spontaneous breath has not been initiated within the selected period. This
may be useful to alert a caregiver when a patient is unable to connect to the mouthpiece or if the patient has fallen asleep.
The device continues to operate. The alarm will automatically terminate when the circuit is reconnected.
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 or equal to 90% of the target tidal
volume setting for at least 1 minute. The alarm will automatically terminate when the calculated tidal volume exceeds 90%
of the target tidal volume for at least 30 seconds.
Note: When AVAPS is on, the Pressure Support Max limit must be reached to enable this alarm.
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.
Low Vti Alarm
This is a high priority alarm. It occurs when the delivered tidal volume is less than the Low 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 exceeds the Low Vti alarm setting.
High Respiratory Rate Alarm
This is a high priority alarm. It occurs when the respiratory rate is greater than the High Respiratory Rate alarm setting.
The device continues to operate. The alarm will automatically terminate when the measured respiratory rate is less than
the High Respiratory Rate alarm setting.
Low Respiratory Rate Alarm
This is a high priority alarm. It occurs when the respiratory rate is less than the Low Respiratory Rate alarm setting. The
device continues to operate. The alarm will automatically terminate when the measured respiratory rate is greater than the
Low Respiratory Rate alarm setting.
