Setting Up For Invasive Use - ResMed Stellar Serie Guide De L'utilisateur

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 (refer to Setup menu:
Options (see page 19)). 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 Valve, or using an uncuffed or deflated cuff
tracheostomy tube with the ResMed Leak Port (24976).
AutoEPAP is contraindicated for invasive use.
WARNING
•
Make sure that all the air inlets at the rear of the device and under the device and vents at the
mask or at the ResMed Leak Valve are unobstructed. If you put the device on the floor, make sure
the area is free from dust and clear of bedding, clothes or other objects that could block the air
inlets.
•
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 a Learn Circuit when a new circuit is used or with a
change of the circuit configuration, in particular when adding or removing high impedance
components (eg, bacterial/viral filter, external humidifier, water trap or different type of air
tubing). Do not connect patient interfaces prior to performing the Learn Circuit. Patient interfaces
include any components placed after the ResMed Leak Valve (eg, HMEF, catheter mount,
tracheostomy tube). Refer to Setup menu: Options (see page 19).
•
Only use HMEFs that comply with the relevant safety standards, including ISO 9360-1 and
ISO 9360-2.
CAUTION
When using a humidifier check the breathing system regularly for accumulated water.
Notes:
•
When the Mask type is set to Trach, the Non-Vented Mask alarm will be automatically enabled to alert
you when the ResMed Leak Valve has no vent holes or when the vent holes are blocked.
•
When the Mask Type is set to Trach, AutoEPAP has to be turned off.
