Spontaneous breathing data
Response pressure of demand valve approx. –1 mbar
Max. delivery at –4 mbar 100 L/min
Sensitivity of synchronization
for SIMV 4 L/min
for SIPPV 3 L/min
Compliance
with 1.5 m ventilation hose <1.0 mL/mbar
with 3.0 m ventilation hose <1.2 mL/mbar
Inspiratory resistance <6 mbar/L/s
Expiratory resistance <4 mbar/L/s
Dead space volume incl. flow sensor approx. 28 mL
Measuring range
Pressure gauge –10 to 80 mbar
Display accuracy ±2 mbar
Max. permissible differential pressure
for flow measurement ±4 mbar
Resistance of flow sensor 3 mbar at 100 L/min
Minute volume measurement
Range 2 to 40 L/min
Accuracy (with O2,
at 1013 hPa, 20 °C,
50 % rel. humidity)
for 1 to 5 L/min ±1 L/min
for 5 to 40 L/min ±12 % of measured value,
but at least ±1 L/min
Patient connection 22 mm ISO conical connector
O2 concentration of the
ventilation gas (with O2 supply)
Switch set to »Air Mix«
for MV less than 7 L/min O2 concentration can increase to 90 vol.%
for MV greater than 7 L/min 60 vol.% O2 ±10 %
Switch set to »No Air Mix« 100 vol.% O2
Response in extreme conditions:
when supply pressure is 10 bar The applied tidal volume VT additionally increases
by approx. 5 % of the set value
Warnings
Supply press. low Warning when supply pressure drops below
approx. 2.0 bar.
Paw high Set via Pmax knob. Warning when set value
for Pmax is reached.
Paw low Warning when a pressure difference >10 mbar is not
built up over a time of >20 s in IPPV/SIPPV or SIMV mode.
