I ntermittent P ositive P ressure V entilation
Volume-controlled ventilation with a fixed mandatory minute
volume MV, set with the tidal volume V
T
and frequency f.
For patients unable to breathe spontaneously, see page 98 for
details.
I ntermittent P ositive P ressure V entilation, Assist
For patients with partial spontaneous breathing.
C ontinuous P ositive P ressure V entilation
Ventilation with continuous positive airway pressure.
This mode is not displayed on the screen as a ventilation mode.
Set IPPV by means of the keys for the ventilation parameters:
— Tidal volume »
V

«,
— Inspiration time » T

«,
— Frequency » f «,
— O

concentration » O

«,
— Positive end-expiratory pressure » PEEP «.
If PEEP is greater than 0 the airway pressure remains
constantly in the positive range (CPPV).
Pressure limit Pmax
The pressure peak can be avoided in IPPV and IPPV
Assist
by
setting a pressure limit. Thereby the PLV ventilation mode can
be reached (Pressure Limited Ventilation).
To set the pressure limit Pmax:
●
Set Pmax to ON, see page 51.
●
Set pressure limit value by means of » Pinsp « key.
●
When setting the pressure limit, ensure that the tidal
volume V
T
is still being applied, as otherwise Savina will
display a "!! Tidal volume low" message. Then:
●
Set pressure limit higher,
or
●
Increase inspiration time » Tinsp .«,
or
● Increase » FlowAcc «,
This can be set on-screen:
Set flow metering by means of »
FlowAcc « on screen page
»Settings 1/1«.
