Connecting a mouthpiece circuit
The mouthpiece circuit is a single limb circuit with no expiratory valve or intentional leak. This circuit is
not intended to support continuous exhalation into the circuit. For patients that may prefer continuous
exhalation into the circuit, a circuit with expiratory valve or intentional leak should be considered.
To connect a mouthpiece circuit:
1. Check the device is fitted with a single limb leak adapter. Otherwise, change the adapter.
Note: The Astral 150 can also support mouthpiece circuit using a double limb adapter.
2. Connect the inspiratory limb to the inspiratory port.
3. Attach any required circuit accessories (eg, filter).
4. Select the circuit type and perform a Learn Circuit.
5. Attach the patient interface (eg, mouthpiece) to the free end of the air tubing as appropriate.
