device (refer to Attaching a bacterial/viral filter (see page 12)).
Note: Other external humidifiers can be used for noninvasive setup. ResMed recommends using a
breathing system (including bacterial/viral filter, air tubings, external humidifier) with an impedance of
maximum 2 cm H
4. Connect one end of the air tubing firmly onto the air outlet of the H4i.
5. Connect the mask system to the free end of the air tubing.
6. Press the power switch on the back to turn on the device.

Attaching the H4i heated humidifier for noninvasive use

Use of the H4i heated humidifier may be recommended by your clinician. For information on using the H4i,
see the H4i user guide.
WARNING
•
Always place the H4i on a level surface below the level of the patient to prevent the mask and
tubing from filling with water.
•
Make sure that the water chamber is empty and thoroughly dried before transporting the
humidifier.
•
The H4i heated humidifier is not intended for mobile use.
•
Do not overfill the water chamber, as during use this will cause water to spill into the air circuit.
Check the air circuit regularly for accumulated water. If you observe water has spilled into the air
circuit, clear the water and check that the water chamber is not overfilled. When using the H4i at
high pressures (above 25 cm H

•
For optimal accuracy and synchrony, perform a Learn Circuit with a change of the circuit
configuration, in particular when adding or removing high impedance components (eg,
bacterial/viral filter, external humidifier, water trap, nasal pillow type mask or air tubing). Refer to
Setup menu: Options (see page 19).
