Compensation level
Compensation level varies from ‘none’ to 100%. If compensation level is 100%, loss of tube pressure
will be fully compensated. Inversely, ‘none’ means that no compensation takes place and that the
Compensation Tube function is not enabled.
As an example, 50% compensation means that only half of loss of tube pressure will be compensated.
CAUTION:
If a compensation level is set, an information message indicating that the func-
tion is enabled is displayed in the alarm banner: «intubation tube compensation enabled».
Tube type
There are 2 types: endotracheal or tracheostomy.
Tube diameter
Internal tube diameter varies from 2.5 mm to 11 mm. According to the patient category selected
(adult, child, infant), suitable minimum and maximum setting limits are available.
CAUTION:
Users must check that the type but also the internal diameter of the tube match
that attached to the patient.
CAUTION:
Compensation is limited to 10 cmH2O.
CAUTION:
For tubes of a diameter smaller than 3 mm, compensation is deliberately un-
der-estimated to avoid barotrauma. Bottom pressure is actually lower than the value dis-
played.
CAUTION:
Ensure there are no leaks in order to prevent barotrauma.
6.2.3 O2 low pressure
This function allows the device to enrich the O2 mix from a low-pressure source (typically, a concen-
trator).
This is different from a high-pressure source connection since it works on a lower scale (pressure gen-
erally less than 1 bar, flow rate less than 10 L/min):
•
Depending on the nature of the source and the ventilation settings, certain FiO2 values cannot be
guaranteed. A chart is provided for information purposes in Technical description on page 102).
•
The mechanisms for monitoring the presence/absence of the source must be adapted.
To activate the “Low Pressure” function, press
[Menu]
, then
[Ventilator configuration]
, then
[Low Pres-
sure O2]
then set the position to “ON”. The “Low Pressure FiO2” descriptive label then appears on the
alarm panel.
