EvitaXL

● Press the key » Sensor Parameter«.
The menu »Sensor Parameter«
is displayed with the »Flow« menu.
Flow monitoring is active.
Start calibration:
● Touch the »Start« screen key. The
key turns green and EvitaXL calibrates
the flow sensor.
EvitaXL uses the next inspiration phase
for the calibration process. Short inspiration
times are extended to approx.
1 second.

Flow calibration
The screen key »Start« turns pale green
when calibration is completed.
External flow compensation
When a constant external flow of up to
12 L/min is supplied (e.g. during medicament
nebulisation with separate gas
supply or during separate tracheal gas
insufflation TGI), this flow can be calculated
by EvitaXL and the tolerance
increased for the monitoring parameters
of the flow sensor in order to avoid generation
of the alarm "Flow measurement
inop." during these applications. The
originally measured expiratory volume is
maintained: EvitaXL measures a correspondingly
higher value for VTe and MV.
The value shown for VTi is too low. The
tidal volume actually applied to the
patient during volume-controlled ventilation
is higher than that set. Pressure-controlled
ventilation is therefore
recommended in combination with an
external flow.
In order to avoid false alarms and ensure
monitoring:
● Adjust both alarm limits for MV in line
with the actual value.
● Use additional monitoring, e.g. SpO2,
if necessary.
For initial calculation of the external flow:
● Start external flow.
