Principles of operation
CAUTION
Risk of incorrect values for resistance and
compliance
If an unused Infinity ID accessory is in the
immediate vicinity of the device, values may be
transferred inadvertently from this accessory.
Do not keep unused Infinity ID accessories in the
vicinity of the device.
CAUTION
Risk of inappropriate compliance values
When accessories are added to an Infinity ID
breathing circuit, the values for compliance and
leakage may deviate from those saved on the
breathing circuit.
Always perform the leakage test before starting
therapy in order to determine the actual values
for compliance and resistance. If the test cannot
be performed because the patient is already
connected, particular attention is required during
ventilation.
CAUTION
Malfunctions of the Infinity ID functionality
Particular EMC situations or defects in Infinity ID
components can cause permanent alarms.
To prevent distracting the user under these
circumstances, contact service personnel to
deactivate the Infinity ID alarms.
Exchange interval monitoring
An automatic monitoring of the period of life is
available for Infinity ID WaterLock 2 water traps,
Infinity ID CLIC absorbers, Infinity ID breathing
circuits, and Infinity ID flow sensors.
An exceeded period of use is signaled during the
system test.
The exchange interval for the connected Infinity ID
accessories can be adjusted.
This interval must be specified in accordance with
the applicable hygiene regulations or the
requirements stated in the instructions for use of
the corresponding accessory.

WARNING
Risk of inappropriate operating life
Exchange monitoring only considers the
absolute period of use and not the current
condition of the Infinity ID accessory and
therefore does not excuse the user from
periodic checks of the accessory.
The exchange interval which can be set for
the exchange monitoring does not represent
a guarantee for the maximum period of use of
the accessory.
Anti-interchange security
WARNING
Risk of interchanged or incorrect breathing
hoses
The Infinity ID function to prevent
interchanging the breathing hoses does not
excuse the user from checking the
accessories.
The Infinity ID function to prevent
interchanging does not represent a guarantee
that the hoses are correctly connected.
When Infinity ID breathing hoses and Infinity ID
breathing bags are used, the incorrect connection
of breathing hoses and the breathing bag is
detected and reported. Hoses that are incorrectly
connected with the breathing system trigger an
automatic alarm.
