Dräger Evita 4 - What was New in Evita 4 Software 2.N

What was new in Evita 4 software 2.n
Pinsp not linked to PEEP during BIPAP
– The ventilation parameter Pinsp is set as an absolute
value. Pinsp is no longer affected by changes in PEEP.
Aids for setting pressure ventilation parameters
– While setting the listed pressure ventilation
parameters, the parameter concerned appears as a
dashed line in the pressure curve Paw.
Continuous indication of the hose system leakage
during the leak test
– The test step "Tightness of hose system" can be
selected separately in the "Device check" menu.
Corrective measures can be undertaken with the aid
of the continuous leakage indication.
Compensation of the hose system compliance
– The hose system compliance determined during the
leak test is indicated at the end of the test.
– The volume-controlled ventilation strokes are
automatically corrected with the calculated hose
system compliance, as are the measured values for
flow monitoring.
Leakage monitoring and compensation
– Evita 4 compares the minute volume delivered on the
inspiration side with that measured on the expiration
side, balances the leakage and indicates this as the
measured value MVleak.
– The applied tidal volume VTi is automatically corrected
by the amount of the measured MVleak. The same also
applies for the Flow and VTe values measured on the
expiratory side.
– The measured minute volume values are not corrected
for safety reasons.
Apnoea ventilation with SIMV pattern
– The patient can breathe spontaneously during apnoea
ventilation.
– The apnoea ventilation frequency remains constant.
AutoFlow

On/Off as start-up parameter
– The AutoFlow

function can be configured as a
start-up parameter so that AutoFlow

is switched on
automatically when the device is switched on.
Loop display also for single strokes
– In addition to the loop for a complete ventilation cycle,
e.g. in IPPV, the loop for a single breath (ventilated or
spontaneous) can now also be displayed, for instance
in such "mixed" ventilation modes as SIMV.
NeoFlow (optional)
– Paediatric flow monitoring in paediatric and neonatal
ventilation is extended to include a flow sensor
specifically for neonates and positioned close to the
patient.
Breathing Support Package (optional)
– To support spontaneous breathing.
– To compensate the elastic and resistive resistance of
the respiratory system.
