Circuit compliance compensation
The ventilator adjusts gas delivery and monitoring to compensate for
the compliance of the patient circuit if:
• The Circuit Compliance is set to On from Super User -
System Config. - Ventilator Settings.
• The Checkout is completed after the system is turned on.
Circuit compliance is measured after Vaporizer Leak test during the
Checkout - Full Test or when the Ventilator Leak check is done as
an individual test. Circuit Compliance must be set by the Super
user for the Circuit Compliance compensation function to be active.
See "Super user mode" section for information on the circuit
compliance setting.
In volume modes, circuit compliance compensation increases the
volume delivered at the inspiratory port by taking into consideration
the circuit compliance value. In all modes, circuit compliance
compensation adjusts the volume measurements. Circuit compliance
compensation provides consistent ventilator accuracy at the patient
circuit.
Breathing circuits and breathing circuit components are available in
many different configurations from multiple suppliers. Attributes of
the breathing circuits such as materials, tube length, tube diameter,
and configuration of components within the breathing circuit, may
result in hazards to the patient from increased leakage, added
resistance, or changed circuit compliance. It is recommended that a
test be conducted prior to use with each patient.
Perform a Full Test or the individual Ventilator Leak test
after changing the patient tube type. Changing the patient
breathing circuit after completing a Full Test or the
individual Ventilator Leak test affects the volume
measurements in all modes.
