CareFusion AVEA - Independent Lung Ventilation (ILV)

104 Chapter 3: Ventilator Operation Operator's manual
L2786 Rev. M
Independent Lung Ventilation (ILV)
Independent lung ventilation allows 2 ventilators to be synchronized to the same breath rate (the rate control set on the
master ventilator), while all other primary and advanced controls for each ventilator can be set independently. Master
and slave ventilators need not operate in the same mode during ILV.
The AVEA offers a port to allow Independent Lung Ventilation (ILV). This connection is located on the rear panel (, C).
The output provides a 5 VDC logic signal, synchronized to the breath phase of the master ventilator.
A specially configured accessory cable kit (part number 16246), available from CareFusion, is required to
implement ILV.
WARNING
Do NOT attempt to connect a standard DB-25 cable to this receptacle. This could cause damage to the
ventilator. A specially configured cable is required for ALL features associated with this connector. Contact
Technical Support.
To enable Independent Lung Ventilation, refer to Chapter 2, Ventilator Setup, Independent Lung Ventilation (ILV).
Note:
During ILV, the alarm limits for each ventilator should be set to appropriate levels for each ventilator to assure
appropriate patient protection. Confirm apnea timer settings and apnea ventilation settings for the Slave ventilator.
These settings will be used in the event of a loss of signal from the Master ventilator.
WARNING
Since the master ventilator controls the breath rate for both ventilators, care should be taken when setting
the other independent breath controls for the slave ventilator, to ensure sufficient time is allowed for
exhalation to occur.
CAUTION
If the cable connecting the master and slave ventilators becomes detached, the slave ventilator will alarm for loss of
signal. In this event, only the master ventilator will continue to provide ventilation at the current settings. The slave
ventilator will begin apnea ventilation after its apnea timer has elapsed at its current apnea ventilation settings.
