6.3.1 Oxygenation function-suction

The [xx% O2 ↗] key is used to ensure the patient has oxygenation, at a FiO2 greater than the current
FiO2. It also makes it possible to inhibit the alarms and ventilation in order to carry out pulmonary aspi-
ration.
Note: If the oxygenation FiO2 is lower than the current FiO2 (see Settings), the button is dis-
abled.
During suction, the PEEP level is maintained to the extent possible, depending on the size of the leak,
in order to limit alveolar derecruitment.
Note: Suction may be carried out according to different methods (fully unplugging the circuit,
opening a connection from the respiratory circuit, or "closed system").
Low-leak methods will be preferred in order to limit alveolar derecruitment.
The Oxygenation-Suction function is organized into three steps:
1- Oxygenation
Once you press the [xx% O2↗] key, the FiO2 that is delivered increases to the value set for oxygena-
tion.
A countdown indicates the time remaining for oxygenation.
If the patient circuit is disconnected or opened to carry out pulmonary aspiration during this oxygena-
tion step (#1), the Suction step (#2) is activated.
Otherwise, the oxygenation turns off and the
[xx% O2 ↗] key turns off.
Note: It is possible to shut down the function at any time by pressing the [xx% O2 ↗] key.
2- Suction
During this step, the ventilator no longer generates ventilation-related alarms.
Additionally, ventilation is interrupted, thereby preventing the secretions contained in this circuit from
spreading. PEEP, however, is maintained, which is improved since the circuit's leak is minimal.
Once aspiration is complete and the patient circuit has been reconnected, the ventilator automatically
detects the reconnection and activates the end-of-suction oxygenation phase.
