Setting Ventilation Modes
SIMV, SIMV/ASB
SIMV, SIMV/ASB
Synchronized Intermittent Mandatory
Ventilation*
Assisted Spontaneous Breathing**
Combines mechanical (volume-controlled)
ventilation with spontaneous breathing.
The patient can breathe
spontaneously between the mandatory
ventilation strokes, contributing to the
total minute volume. The spontaneous
breaths can be supported with ASB.
Mandatory ventilation strokes ensure a
minimum level of ventilation in the times
in between. This minimum ventilation is
determined via the two set parameters
tidal volume »VT« and frequency »f« and
is the product of VT x f.
The frequency can be reduced to zero
during the weaning process. The device
automatically changes to the ventilation
mode CPAP or CPAP/ASB. This ventilation
mode is also indicated on the
screen. The screen key »SIMV« and the
screen knobs for setting the SIMV
parameters remain on display.
Set the pattern of ventilation for SIMV
and SIMV/ASB with the ventilation
parameters:
Tidal volume »VT«
Insp. Flow »Flow«
Frequency »f«
Inspiration time »Tinsp«
O2 concentration »O2«
Positive end-expiratory pressure »PEEP«
Pressure support »PASB«
Pressure rise time »Ramp«
