TROUBLESHOOTING

The following information is intended to help you troubleshoot and solve simple

operational problems that you may experience when using your HELiOS

Portable.

1. The Portable makes a hissing sound.

Hissing can occur to maintain the correct operating pressure within the

Portable. It is most likely to hiss after filling or when the position of the

Portable is changed. Hissing can last for approximately 10 minutes after

filling. Additionally, it can occur when the flow control valve is at a low

setting.

2. The Portable does not pulse after filling.

If during the filling process, the Portable is disengaged with the vent valve

lever down, pressure may be reduced within the Portable causing a delay in

the conserving device function. It may require as much as 60 minutes to

restore adequate pressure for accurate oxygen flow. Additionally, improper

filling or lower than normal operating pressure in the Reservoir will

contribute to the unit not pulsing.

3. The Portable stops pulsing during use.

• Ensure that both connections of the dual lumen cannula are firmly attached

to the Oxygen Outlet and Sensor connectors.

• Change the cannula if water droplets are present from humidified exhaled

gas. Replacing the cannula with a dry one enhances the ability of the

Portable to pulse.

• Ensure that the cannula is not kinked.

• Ensure that the cannula tips remain in your nostrils and do not slide to one

side.

• Ensure that there is oxygen in the Portable.

• With the cannula on, close your mouth and breathe only through your nose

to verify that the Portable has stopped pulsing.

4. The Portable does not fill.

• Verify that there is oxygen in the Reservoir.

• Ensure that the Portable and Reservoir fill connectors are fully engaged

throughout the filling process.
