10.9 SIMV
10.9.1 Functional description SIMV
SIMV is a combination mode where the patient
receives mandatory breaths synchronized with
his breathing efforts and according to the
selected SIMV mode. The patient can breathe
spontaneously with Pressure Support in
between the mandatory breaths.
There are two different SIMV modes,
depending on the modes installed:
• SIMV (Pressure Control) + Pressure Support
• SIMV (Volume Control) + Pressure Support
During the SIMV period, the first triggered
breath will be a mandatory breath. If the
patient has not triggered a breath within the
first 90% of the Breath Cycle time a mandatory
breath will be delivered.
If the system is configured for setting of
Inspiration time, an I:E ratio of 1:3 (Adult) or
1:2 (Infant) will be used to estimate the Breath
cycle time.
The spontaneous/pressure supported breaths
are defined by setting the Pressure support
level above PEEP.
