Volume AF is a pressure controlled ventilation
mode with a guaranteed tidal volume V
quency Freq. as well as optional synchronization
activation and variable pressure support for sponta-
neous breathing efforts (optional).
Volume AF combines the advantages of pressure
controlled and volume controlled ventilation mode.

ing the ventilation with Volume AF, the first manda-
tory breath is volume controlled in order to identify
the necessary pressure level, if not known from a
previous ventilation mode.

Primus automatically adapts the inspiratory pres-
sure to the changing lung condition from breathing
cycle to breathing cycle in steps of max. +3 mbar.
The delivery of tidal volume for one breathing cycle
is limited to 130 % of the set tidal volume. If the vol-
ume limitation is active, the ventilation pressure for
the following breath will be reduced to 75 % of the
target pressure, but limited to a maximum of
15 mbar above PEEP.
Some settable values are limited or mutually exclu-
sive so that specific combinations of therapy set-
tings are not possible, e.g., T
