This ventilator circuit carries an external exhalation valve in the patient circuit rather than in the ventilator. It is used with ventilators that require the valve to be fitted at the circuit, and each circuit is supplied complete with the valve, its control line and a catheter mount. Adult circuits are available in 1.6 m and 1.8 m, with optional nebulizer kit or water trap.
Not every ventilator has an exhalation valve inside the machine. Some ventilators — particularly transport ventilators, some older ICU machines and certain neonatal devices — are designed to work with the exhalation valve fitted in the patient circuit, where the ventilator drives the valve through a control line.
This matters when ordering. A circuit with an external exhalation valve is not interchangeable with a standard circuit: a standard circuit has no valve, so the patient cannot exhale against a controlled pressure, and a valve circuit connected to a ventilator that already has an internal valve will not work either. The circuit has to match the ventilator.

Key Features:
External exhalation valve fitted in the patient circuit
Control line included for ventilators that drive the valve
Catheter mount in corrugated or smoothbore form
Nebulizer kit available on selected configurations
Water trap available on the 1.8 m configuration
1.6 m and 1.8 m adult circuits
Applications:
Ventilators that require the exhalation valve to be fitted in the patient circuit
Transport ventilation
ICU ventilators without an internal exhalation valve
Where a nebulizer kit is needed in-line
Where condensate control is needed on a valve circuit
Important Notes:
Confirm that your ventilator requires an external exhalation valve before ordering. This circuit is not interchangeable with a standard ventilator circuit.
Connect the control line to the correct port on the ventilator. An incorrectly connected or kinked control line will prevent the valve from cycling.
Check that the exhalation valve is correctly seated and that its diaphragm is undamaged before use.
Position the valve so that condensate cannot reach it. Fluid in the valve will cause it to stick.
If a water trap is fitted, place it at the lowest point of the circuit and empty it before it reaches the fill line.
Check that all connections are secure before use.
Do not allow the tubing or the control line to kink or become trapped.
Single use only unless the circuit is specified as reusable.
This product is a breathing circuit. It does not provide ventilatory support on its own.
