The Resmed Stellar 150 ventilator can be used for bi-level positive airway pressure (BPAP) therapy. The device blows air under two different pressures through a mask. A higher pressure is used to help fill the lungs with air when breathing in and a lower pressure is used when breathing out to prevent the airway from closing.
Assembling the circuit and filling the water chamber on the Resmed Stellar 150 ventilator
The Resmed Stellar 150 ventilator is provided by the Ontario Ventilator Equipment Pool (VEP). This is a branch of the Assistive Devices Program (ADP).

Watch the video to learn how to:
- attach the H4i heated humidifier to the Resmed Stellar 150 flow generator
- connect the power cord to the socket on the rear of the flow generator
- attach the long tubing to the air outlet. The other end of the long tubing is connected to the mask when you are ready to use it.
- fill the water chamber
- check the circuit to make sure everything is connected properly and to make sure the exhalation port is working

Starting and stopping therapy on the Resmed Stellar 150 ventilator
Watch the video to learn how to start therapy by:
- starting the machine
- confirming the unit is on
- checking for leaks around the mask
- making sure there is flow coming from the exhalation port on the mask
- making sure your child is breathing comfortably
Learn how to stop therapy by:

Performing a learn circuit on the Resmed Stellar 150 ventilator
A learn circuit can assess and adjust to the changes in the circuit, and the type of mask and connectors being used. It helps the machine learn the flow, optimize therapy and monitor for accuracy. A learn circuit is recommended:
- whenever you change the mask
- any time you add or remove connectors
- when you add or remove the humidifier from the machine
Watch the video to learn how to perform a learn circuit.
Setting ramp on the Resmed Stellar 150 ventilator
Ramp is a feature on the Resmed Stellar 150 that allows you to set how long it takes until the prescribed pressure is reached. It allows pressure to increase slowly and gently. This makes it easier for your child to tolerate ventilation pressure as they fall asleep.
Watch the video to learn how to set the ramp duration.
