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.

•For optimal accuracy and synchrony, perform Learn Circuit with a change of the circuit configuration, in particular when adding or removing high impedance components (eg, antibacterial filter, external humidifier, water trap, nasal pillow type mask or air tubing). See “Setup menu: Options” on page 16.

CAUTION

Check the air circuit for water condensation. Use a water trap or a tubing wrap if humidification is causing water condensation within the tube.

Notes:

•A humidifier increases resistance in the air circuit and may affect triggering and cycling, and accuracy of display and delivered pressures. Therefore perform the Learn Circuit function (see “Setup menu: Options” on page 16). The device adjusts the airflow resistance.

•The heating feature of the H4i is disabled when the device is not mains powered.

Setting up for invasive use

The Stellar can be used invasively only with the ResMed leak port and an uncuffed or deflated cuff tracheostomy tube.

WARNING

• When using a Heated Moisture Exchange Filter (HMEF), replace the HMEF regularly as specified in the instructions provided with the HMEF.

•The H4i is contraindicated for invasive use. An external humidifier approved for invasive use is recommended according to EN ISO 8185 with an absolute humidity of > 33 mg/L.

•For optimal accuracy and synchrony, perform Learn Circuit with a change of the circuit configuration, in particular when adding or removing high impedance components (eg, antibacterial filter, external humidifier, water trap, nasal pillow type mask or air tubing). See “Setup menu: Options” on page 16.

CAUTION

When using a humidifier check the breathing system regularly for accumulated water.

Note: When the mask type is set to Trach, the Non-Vented Mask alarm will be automatically enabled to alert you when the leak port has no vent holes or when the vent holes are blocked.
