Note:
Expiratory Minute Volume: Low
Considerable leakage may occur around the endotracheal tube if it is uncuffed. The combination of
small tidal volumes, leakage around the tube and activated compliance compensation may trigger the
Low Expiratory Minute Volume
alarm, due to a very low expiratory flow passing from the patient
through the expiratory channel. By observing the difference between the Vti and Vte values presented
on the screen, a leakage can be detected and its extent easily controlled. The first time an
unacceptably large leakage occurs around the tube, correct this problem to avoid triggering this alarm.
If leakage persists, adjust the alarm limit to its lowest level (10 ml) if this is clinically appropriate.
Finally, if the leakage still has not been remedied, deactivate the compliance compensation to avoid
triggering the alarm. If the compliance compensation is deactivated from Pressure Control, Pressure
Support, or SIMV (Pressure Control) ventilation modes, then no further settings need to be adjusted.
However, if volume-related modes are used, the set volumes must be adjusted.
