7 Description of the modes
The IPPV mode is used for mandatory volume-controlled
ventilation with a fixed tidal volume and fixed frequency. This
mode is used on patients who have no spontaneous breathing.
However, a spontaneously breathing patient can breathe deeply
and freely during expiration.
When the maximum ventilation pressure (pMax) is achieved, the
device maintains the pMax up until the end of the inspiration time
and then switches to expiration. As such, the set tidal volume is
possibly not fully applied if the maximum ventilation pressure
(pMax) is achieved during inspiration.
