Hoses, filters, cables, and breathing bags
Additional components or certain hose configurations may alter the values for
leakage, compliance, and inspiratory and expiratory resistances and thus affect the
therapy. Consequently, the patient may be put at risk, e.g., the tidal volume may
deviate.
► When using configurations that deviate from a standard breathing circuit, the
user must pay particular attention to the measured values.
► Perform a leakage test after replacing breathing hoses, particularly extendable
hoses, vaporizers, soda lime, or other components.
► Perform a leakage test after changing the length of extendable hoses.
► Do not use extendable hoses to ventilate neonates.
As a result of leakage, ambient air may get into the breathing gas, breathing gas
may escape, or contamination of the connected central supply may occur.
The patient or the user may be put at risk due to the following:
– Reduction of the depth of anesthesia
– Incorrect gas measurements
– The applied volume is less than the set volume.
– Accumulation of anesthetic gas in the ambient air
– Contamination of the supply gases
– The sample line is damaged.
– The CO
► Connect the sample line correctly.
► Perform the leakage test before using the device. Rectify the leakage or reduce
it to a minimum.
► If the central supply fails during operation, disconnect the hoses for the failed
gas from the central supply.
► After mounting and replacing, make sure the CO

► Check the inner hose for leakage. With Dräger hoses, use the appropriate test
adapter. Next, perform a leakage test on the entire breathing circuit. Observe the
following information: "Checking a coaxial breathing circuit for leaks with the
leakage assistant", page 117.
