Patient Circuits
For instructions on attaching circuits to the ventilator, see the “Device Setup” chapter.
Circuit Principles
Each patient circuit has a different compliance and resistance. During Circuit Calibration, the ventilator verifies that the maximum pressure drop
does not exceed the specifications below. For optimal performance, calibrate the circuit before using it with a patient. See “Circuit Calibration” in
the “Device Options” chapter.

the “Device Options” chapter.
When adding any components to the breathing system, the flow resistance and dead space of the added components such as humidifiers, speaking
valves, Heat Moisture Exchangers (HMEs) and filters should be carefully considered in relation to the potential for adverse effects on the patient’s
ventilator management and device alarms.

ventilator management and device alarms.
If a breathing system filter is exposed to nebulization or humidification, to prevent increased resistance or blockage, the breathing system filter
requires replacement more frequently.

Circuit Requirements
For safe operation, the ventilator requires a patient circuit and filter(s) that meet the following requirements.
Compliance: up to 4 ml/cmH

Leak Compensation
The passive circuit provides leak compensation for inhaled and exhaled tidal volume measurements. This includes compensation for intentional
leak in the patient circuit and leaks that occur at the patient interface, such as cuff leak or mask leak.
leak in the patient circuit and leaks that occur at the patient interface, such as cuff leak or mask leak.
The active flow and dual limb circuits compensate for leak that occurs between the ventilator and the external flow sensor. Leaks that are
downstream of the external flow sensor are not compensated for in measurement of inhaled or exhaled tidal volume.
downstream of the external flow sensor are not compensated for in measurement of inhaled or exhaled tidal volume.
Leak compensation is not available in the active PAP circuit.
