Apnea ventilation is triggered when no inspiration has been triggered for a time greater than T apnea.
It stops when:
•
The patient triggers more than three consecutive cycles,
•
The user presses the apnea ventilation Off key,
•
The user changes ventilation modes.
The ventilation of apnoea may be deactivated in CPAP mode by setting the apnoea T set-point to OFF.
In such a case, an alarm sounds to confirm deactivation and should be acknowledged.
CAUTION:
For safety reasons, the ventilation of apnoea should only be deactivated where
the clinical situation allows. Air Liquide Medical Systems recommends that apnoea ventila-
tion is activated.
Note:
Ideally, the apnea ventilation adjustment should be performed before starting ventila-
tion.
To access the apnea ventilation adjustments, press the
[Menu]
key and then
[Apnea ventilation set-
tings]

6.2.2 TC (Tube Compensation)
[Patient circuit compensation]
In invasive ventilation, the tube compensation function is used to estimate tube end pressure (at the
tip of the tube) by making up for pressure loss in the intubation tube (tube resistance according to
flow rate). By therefore applying the pressure level, set not at the pressure measured in the Y piece but
at bottom pressure, the patient’s physiological needs will be met.
When the function is enabled, two pressure curves are displayed: Y piece pressure (unbroken line) and
bottom pressure (dotted line).
Note:
The TC function is only available for the following pressure modes: PCV, PSV, SIMV,
and for spontaneous PSIMV, PRVC and PS-Pro cycles. Compensation only applies during the
inspiratory phase. The function remains enabled when users change modes during ventila-
tion, but becomes disabled when the device returns to Standby mode.
To enable the function, press the
[Menu]
button then the
[TC]
key.
Three parameters are available:
•
Compensation level;
•
Tube type;
•
Tube diameter.
