5 Operation Methods of Various Ventilation
Modes
5.1
C: also called control respiration
The characteristic is that patient cannot control releasing airflow, and all respiratory movement all
must be carried out according to the conditions set by ventilator.
Operation methods is as following:
a) Set the breath frequency
f
.
b) Set the ventilation volume
c) Upper limit setting for airway pressure: it can be set higher when turn on the ventilator, read the
airway pressure peak value from the airway manometer after ventilator runs normally in A/C mode,
then set the upper pressure limit 1kPa higher than the airway pressure peak value.

5.2
A: Namely assist respiration
It is featured by that the patient can control the respiration frequency, while the tidal volume of the
respiration, the time of the inspiration and expiration are still controlled by ventilator. To the patients
who remain fully conscious and have spontaneous respiration ability, but can’t conduct enough
breath function, the assist respiration of the ventilator is needed.
a) Control the ventilation frequency
f
, the set value should be lower several times every minute
than
f
total,
b) Set the burst electrical level: adjust around –0.3kPa.
To A, several above-mentioned parameters must be adjusted properly and must assist with vigor
analysis. Other parameters adjustments are all same to C.
