determined for volume correction and
the overall system is checked for leaks in
the breathing system.

tested at the same time.
Leakage is tested in the automatic
(mechanical) ventilation line (leakage,
system) and in the overall system
(leakage Man./Spont.).
Display:
The clock symbol disappears when the
test is complete and Primus displays the
values for system compliance, leakage
(system) and leakage Man. Spont. if
applicable (values >150 mL/min), see
"Leakage", page 40.
The results of the leak test are displayed
on the data screen at all times.
To return to the standby screen:

A new screen is displayed.
