Instructions for use Primus Infinity Empowered SW 4.5n 117
Operation
The value for the ventilation parameter T
INSP (B)
automatically turns yellow and is adjusted at the
same time. The ratio of inspiration to expiration I:E
remains constant.
Changes in PEEP
Depending on the configuration, the pressure limit
value PINSP can also be changed automatically
when changing the PEEP value, see page 176.
For automatic P
INSP adjustment:
1 Press the soft key PEEP (A), key lights up yel-
low.
2 Set and confirm the ventilation parameter PEEP
via the rotary knob.
The value for the ventilation parameter P
INSP (B)
automatically turns yellow and is adjusted at the
same time.
If configured, the lower alarm limit for the airway
pressure PAW (C) will be automatically changed
when the PEEP value is changed.
Changes in TINSP
TSLOPE may be reduced simultaneously if TINSP is
reduced.
Changing between ventilation modes
When changing to a different ventilation mode, the
pre-settings are adopted or appropriately derived
from the parameters of the preceding mode.
Parameters which are identical in both ventilation
modes are adopted directly (freq., TINSP, PEEP,
∆
PPS, Trigger) (A).
When changing from volume-controlled to pres-
sure-controlled ventilation:
The measured parameter PLAT is adopted as the
new value for P
INSP (B).
When changing from pressure-controlled to vol-
ume-controlled ventilation:
The new tidal volume V
T is calculated based on the
measured minute volume MV and set frequency
Freq.. Only the minute volume applied by the ven-
tilator is taken into account. Pressure supported
breathing strokes by the patient are disregarded.
When changing from automatic ventilation modes
to Pressure Support Mode (optional):
The set PEEP,
∆
PPS, and Trigger are adopted.
If
∆
PPS or Trigger were set to OFF, the last values
used are adopted in Pressure Support mode. The
configured default settings are used in all other
cases.
