Attaching patient circuit accessories

WARNING
Adding or removing circuit components can adversely affect ventilation performance.
ResMed recommends performing a Learn circuit every time an accessory or component is
added to or removed from the patient circuit.
Do not use electrically conductive or anti-static air tubing.

Attaching a humidifier

A humidifier or HME is recommended for use with the Astral device.
WARNING
For invasive ventilation, since the patient's upper respiratory system is bypassed by an
artificial airway device (for example endotracheal or tracheostomy tube) humidification
of the inspired gas is required to prevent lung injury.
Always place the humidifier on a level surface below the level of the device and the
patient to prevent the mask and tubing filling with water.
Only use humidifiers that comply to the relevant safety standards, including ISO 8185
and set up the humidifier according to the manufacturer's instructions.
Monitor the air tubing for water condensation and / or spillage from the humidifier.
Use appropriate precautions to prevent water in the circuit transferring to the patient
(eg, a water trap).
For non-invasive ventilation, for patient experiencing dryness of the nose, throat or mouth,
humidification of the inspired gas will prevent subsequent irritation and discomfort.
CAUTION
Make sure that the water tub is empty and thoroughly dried before transporting the
humidifier.
To attach a humidifier to a patient circuit:
1. Connect a length of air tubing to the inspiratory port on the device.
2. Connect the other end of the air tubing to the inlet port on the humidifier.
3. Connect the patient circuit to the outlet port on the humidifier.
