Equipment parameters

Principle of operation
Control principle
Trigger sensitivity
Trigger delay time (time from the start of sponta-
neous inspiration to the start of a synchronised
mandatory ventilation stroke)
Positive end-expiratory pressure PEEP or continuous
positive airway pressure CPAP
System compliance with hose system without
humidifier
System resistance at 30 L/min and 5 L/min,
respectively
Hose system
Hose system F&P 84 11 041
Hose system HFV F&P 84 11 153
Other hose systems
Use other hose systems only if their resistance does not exceed the specified values since the measurement of the airway
pressure may otherwise be affected.

Babylog 8000 plus ventilates on the continuous-flow principle with
time control and and is pressure limited.
Oxygen is added to the air with an integrated air-oxygen mixer.
Continuous flow, expiration valve, pressure-limited, time-controlled
1 to 10 corresponds to about 0.02 to 3 mL
Typically 40 to 60 ms [see explanation on page 126]
0 to 25 mbar
<1.0 mL/mbar
Inspiratory resistance
12 mbar/30 lpm = 24 mbar/L/s
...
<11 mbar/30 lpm = 22 mbar/L/s
Two differential pressure sensors within the ventilator measure the
pressures, relative to the atmospheric pressure, at the inspiration
and expiration connectors of the hose system. The pressure at the
Y-piece is calculated from these two values (see the explanation on
page 124).
