6.12 Compensation functions
6.12.1 Leakage compensation
Leakage compensation is automatic for all
patient categories in non invasive modes.
The function is designed to help maintain
PEEP throughout the breath and is activated
by default.
Leakage compensation may also affect
important ventilatory parameters, such as
patient triggering and the termination of
inspiration.
Leakage is measured and presented in
percent.
6.12.2 Circuit compensation
Part of the volume of each inspiration will not
reach the patient because of gas compression
in the ventilator and expansion of the tubing.
All components in the patient circuit affect
such losses.
When circuit compensation is activated, the
delivered and measured volume and flow
values are automatically compensated for
these losses, as indicated by the symbols on
the affected values.
The patient circuit test must be passed in
order to activate circuit compensation.
To deactivate or reactivate, tap
COMPENSATION in the extended
menu/CIRCUIT COMPENSATION. Follow
on-screen instructions.
Important: When monitoring VT/PBW,
circuit compensation must be activated.
