초록 ▼

The invention relates to the supply of superoxygenated air to a patient during a part of the inspiratory phase. An electrically controlled supply valve is opened as soon as the sensor of a detector receives a depression signal due to a start of inspiration. This produces a voltage which is compared with a reference voltage corresponding to the atmospheric pressure previously stored in a memory. The duration of the injection is counted and is proportional to the duration of the non-injection which is dependent on the duration of the expiratory phase.
