Apnoea ventilation
For automatic switchover to volume-controlled mandatory

volume-controlled mandatory ventilation with:
— inspiration /expiration ratio I:E = 1:2
and the set ventilation parameters:
— Frequency »fApnoea«

The patient can breathe spontaneously during apnoea
ventilation. The frequency »fApnoea« remains constant.
