Considerable leakage may occur around the ble leakage may occur around the
endotracheal tube if it is uncuffed. The f it is uncuffed. The
combination of small tidal volumes, leakage kage
around the tube and activated compliance pliance
compensation may trigger the Low
Expiratory Minute Volume alarm, due to a
due to a
very low expiratory flow passing from the m the
patient through the expiratory channel. By
observing the difference between the Vti and
bserving the difference between the Vti and
Vte values presented on the User Interface, a ues presented on the User Interface, a
leakage can be detected and its extent easily ge can be detected and its extent easily
controlled. The first time an unacceptably first time an unacceptably
large leakage occurs around the tube, occurs around the tube,
correct this problem to avoid triggering the ggering the

still persists, adjust the alarm limit right down djust the alarm limit right down
to its lowest level (i.e. 10 ml) – if this step is 10 ml) – if this step is
