Paediatric use
Infant hose set
Infant hoses must be used for ventilation volumes of less
than 200 mL.
If a breathing gas humidifier is used, water traps must be
installed at the lowest points of the breathing hoses on
both the inspiratory and the expiratory side.
Avoid pressure peaks
The fresh gas is stored in the breathing bag during
inspiration. The pressure built up in the breathing bag
when working with high flow rates and long inspiration
times may be higher than the end-inspiratory pressure
in the patient, particularly when using a 0.5 L breathing
bag.
Even at a fresh gas flow of 4 L/min, a pressure peak may
arise at the beginning of the expiration phase as fresh
gas streams out of the breathing bag. This is particularly
possible in combination with long inspiration times and
can be avoided by reducing the fresh gas flow or using
a 1.5 L breathing bag.
The adjustment intervals and metering accuracy for the
tidal volume VT depend on the selected range.
Range Interval
< 20 mL 1 mL
20 to 50 mL 2 mL
50 to 100 mL 5 mL
100 to 990 mL 10 mL
1 L to 1.4 L 0.01L
The system must calculate its new system compliance
following a change of hoses.
The patient must be disconnected for this
[
purpose and the leakage test started!
(see overleaf)
The ventilation parameters are adjusted in the same way
as in IPPV mode.
If a tidal volume of less than 200 mL is selected from a
higher setting, the system automatically generates the
