It occurs when the
• • •
• •
delivered pressure
exceeds the target
patient pressure during
the expiratory phase by
5 pressure units. This
may be due to pinched
tubing or the patient
having a fast breath
rate. The alarm will
automatically terminate
when the delivered
pressure comes within
5 pressure units during
the expiratory phase.
It occurs when the
• • •
• •
delivered pressure is 5
pressure units or more
below the target patient
pressure during the
expiratory phase. The
alarm will automatically
terminate when the
delivered pressure
comes within 5
pressure units of the
target patient pressure
during the expiratory
phase.
It occurs when there is
• • •
• •
a leak in the internal air
delivery system that
allows oxygen to build
up inside the device.
The alarm is generated
when the internal
oxygen concentration
reaches 5% above
ambient levels.
