6.6 Ventilation Type
The ventilator provides two ventilation types: invasive and non-invasive. Invasive ventilation
is the default ventilation type.
6.6.1 Invasive Ventilation
Invasive ventilation means to ventilate the patient through manual airway (endotracheal
intubation or tracheostomy). In invasive ventilation, all ventilation modes for adult and
pediatric patients are enabled. In invasive ventilation, ATRC function can be set.
The calculated leakage is compensated up to 80 % of the set tidal volume in invasive mode.
6.6.1.1 ATRC
ATRC refers to automatic tube resistance compensation function, which the ventilator can
adjust the input pressure to keep the pressure of the tube end and pressure set on the
ventilator to be the same as possible for endotracheal intubation or tracheotomy intubation of
the different tube diameters that the user chooses.
ATRC can be set on the parameter setting interfaces of each mode.
1. Select a ventilation mode, and select [ ATRC ] to enter the ATRC interface.
2. Set the intubation type, tube diameter and the proportion of compensation.

Intubation type: endotracheal intubation or tracheotomy intubation.

Tube diameter: the tube diameter of intubation.
 Compensation proportion: the percentage of ATRC.

Compensation of expiration procedure : turn on or off the compensation of
expiration procedure.
3. Select [ OK ] to turn on the ATRC function. If ATRC function is turned on, select
[ Disable ATRC ] on the ATRC interface to stop the ATRC function of the ventilation
procedure immediately.
WARNING

ATRC function may induce autotriggering. If autotriggering occurs, first check the
patient, breathing circuit, and other settings as possible causes before lowering the
Compensate setting or disabling ATRC.

If intubation type and pipe diameter are set incorrectly, it may cause harm to
patients. Please set intubation type and pipe diameter correctly.
