Leak test
This test must be performed:
— after the device check,
— after changing the hose system,
— after changing the humidifier.
In the checklist:
● Touch the screen key »Airtight
Check«.
The result of the last leak test is displayed
together with the following values:
— Leakage
— Compliance
— Insp. Resistance
— Exp. Resistance
To start the leak test:
● Touch the screen key »Check«.
The actual leakage flow is displayed continuously
throughout the test. A leakage
flow of 300 mL/min at a pressure of
60 mbar is permissible.
After the leak test, the ventilator determines
the compliance and the inspiratory
and expiratory resistance of the
hose system.
The established compliance of the hose
system is used by the ventilator for automatic
correction of the volume-controlled
ventilation strokes, as well as of the
measured values for flow monitoring,
see page 218.
When changing the patient mode or
type of humidifier, the ventilator automatically
resets the values for hose compliance
and hose resistance to the default
values.
To return to the start screen:
● Touch the screen key »Start/
Standby« in the »Start/Standby«
menu.
