Using Bacterial Filters - Dräger Carina Instructions For Use Manual

Assembly and preparation
Note the following for a passive humidifier
A heat and moisture exchanger (HME) for a pas-
sive humidifier may significantly increase the resist-
ance at the patient connection. An increase in re-
sistance will result in increased breathing effort with
spontaneous breathing or increased trigger effort
with assisted breathing. Under unfavorable circum-
stances this may result in unwanted intrinsic PEEP.
The device cannot directly monitor resistance in the
patient connection.
For this reason:
 Check the patient state and the volume values
of the device more frequently.
 Observe the instructions for use for the HME.
 Do not use additional inspiratory bacterial filters
with a heat and moisture exchanger with filter
function.

Using bacterial filters

WARNING
Risk of infection
Do not operate the device without an inlet fil-
ter (HEPA filter) to prevent infection of the pa-
tient and to ensure dust-free operation.
WARNING
Risk of infection
If no inspiratory bacterial filter is used, the pa-
tient can be infected by aspirated ambient air.
Use an inspiratory bacterial filter.
 Fit the bacterial filter
port.

onto the inspiratory
WARNING
Increased resistance
If an HME and a breathing gas humidifier/med-
ication nebulizer are used at the same time, re-
sistance can increase.
Use either an HME or a breathing gas humidi-
fier/medication nebulizer.
WARNING
Increased resistance
When using a heat and moisture exchanger in
environments with high relative humidity, the
resistance may be significantly increased. In
some cases the device may not detect a dis-
connection in this situation.
Assess the necessity of using the HME under
these conditions or connect an appropriate
external monitor to the breathing circuit.
