Safety information on breathing circuits
and additional components
Additional components in the breathing circuit can
increase the inspiratory and expiratory resistance
values and exceed standard requirements.
Examples of additional components:
– Bacterial filters, inspiratory and expiratory
– CO cuvettes
2
– Coaxial hoses
CAUTION
Increased compliance or resistance
Additional components in the breathing circuit
such as bacterial filters or CO
the dead space, compliance, and resistance in
the breathing circuit. Depending on the
ventilation mode, either flow or pressure
increases.
Particular care and monitoring are required when
using additional components.
Using bacterial filters
The ventilator is designed to minimize the patient's
work of breathing. The use of bacterial filters
requires particular care and monitoring by the user.
Especially during medication nebulization and
humidification, the resistance of the expiratory
bacterial filter may increase gradually.

Consequences of high resistance
High resistance values during assisted ventilation
lead to increased work of breathing and trigger
effort. Under unfavorable conditions, this can lead
to an undesirable, intrinsic PEEP, which can be
recognized by the fact that the expiratory flow does
not return to baseline at the end of expiration. If the
PEEP is unacceptably high, this is indicated by an
alarm. This indicates that the measured PEEP is
more than 4 mbar (4 cmH
Check the bacterial filter and replace it if this is the
cause of the PEEP alarm. If the end-expiratory
flow is high, the alarm threshold increases to a
measured PEEP value of up to 12 mbar
(12 cmH O).

Monitoring resistance
Because the device cannot measure resistance at
the patient connection, carry out the following
measures:
 Check the patient's condition regularly.
 Monitor the device's measured values for
volume and resistance.
 Observe the instructions for use for the
bacterial filters and breathing circuits in use.
Preparing the breathing gas humidifier
Condition: The combination of breathing gas
humidifier and Babylog 8000 must not impair the
safety and function of either device.
 Prepare the breathing gas humidifier in
accordance with the corresponding instructions
for use.
Assembly and preparation
