IPPV, IPPVAssist, CPPV
Intermittent Positive Pressure Ventilation
Volume-controlled ventilation with a fixed mandatory minute
volume MV, set with the tidal volume VT and frequency f.
For patients unable to breathe spontaneously, see page 98 for
details.
Intermittent Positive Pressure Ventilation, Assist
For patients with partial spontaneous breathing.
Continuous Positive Pressure Ventilation
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 »VT«,
— Inspiration time »Tinsp«,
— Frequency »f«,
—O2 concentration »O2«,
— 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 IPPVAssist 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 VT 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«.
