EvitaXL

Apnoea Ventilation
For automatic switch-over to volume-controlled
mandatory ventilation if the
patient stops breathing.
It can be switched on in the ventilation
modes SIMV, BIPAP, CPAP, APRV.
EvitaXL outputs an apnoea alarm if no
expiration flow is measured or insufficient
inspiratory gas is delivered during
the set apnoea time TApnoea > (adjustable,
see "Setting alarm limits", page 79).
EvitaXL will then start volume-controlled
ventilation with the set ventilation parameters:
Frequency »f«
Tidal volume »VT«
The ventilation parameters »O2« and
»PEEP« correspond to the settings
effective at the time. The inspiration time
for apnoea ventilation is determined
from the set frequency »f« and a fixed
I:E ratio of 1:2.
As in SIMV, the patient can breathe
spontaneously during apnoea ventilation,
and the mandatory ventilation
strokes will be synchronised with the
patient's spontaneous breathing.
The apnoea ventilation frequency
remains constant.
