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.
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.
