By no means does our troubleshooting information cover every possibility, but sometimes a simple fix can be discovered and save everybody time, getting the equipment back up and running as fast as possible. As always, do not hesitate to call us if you are having difficulties with your equipment.

The Basics
Some of the first things to check when troubleshooting any of our equipment are not necessarily equipment-related. Below are NRS' suggested first steps for troubleshooting non-functional equipment:

Is the equipment getting power?
For equipment that requires electricity to operate, make sure the cord is plugged in both at the outlet and on the back of the machine, if applicable. Also, make sure the outlet is operational by checking the electrical breaker box and/or plugging a working lamp into the outlet to test it. Some outlets may have test buttons that have "popped" and need to be reset.

Are the connections misaligned?
For both concentrators and liquid oxygen, the adapters or humidifier bottles may be misaligned and need to be re-threaded to make the needed seal. Be sure to check tubing connections as well for snugness and a good seal.

Is the oxygen tubing free flowing?
Nasal cannulas and tubing can get kinked or pinched by the machine or other nearby objects. Verify that a chair or wheel under the oxygen equipment is not on top of the tubing obstucting the oxygen flow. Humidifier bottles will emit a whistle sound when oxygen flow is obstructed.
