Q. How often does my oxygen concentrator need to be serviced?
A. Manufacturers’ guidelines recommend a maintenance check once per year. At this time, our technician will check the operation of your concentrator and may change filters and tubing at that time.
Q. What do I do if my equipment breaks down?
A. Give us a call or stop by any of our offices. Reliable will send your equipment in for evaluation and provide you with a rental product for use while yours is being repaired. We will check to see if your equipment is covered under warranty or if insurance will cover repair and/or replacement.
Q. I am getting a lot of water in my CPAP/Bilevel tubing and mask. Why is this happening and how do I stop it?
A. This is called rain-out and often occurs when the air in the room is cooler than the air coming out of your humidifier. You can decrease the heat setting on your humidifier, if a lower setting is comfortable for you. Reliable also has a selection of tubing insulators that can be purchased in our offices. These insulators wrap around your tubing to keep the air temperature more consistent and provide you with the humidity you need without that irritating rain-out.
Q. I have a sore on the bridge of my nose from my CPAP mask. How do I fix this?
A. If your mask worked well to begin with, you may just need a new mask cushion. Over time, the silicone in the cushion will break down with normal use. Regular replacement of your supplies will keep the materials fresh and well-fitting. See CPAP/Bilevel replacement guidelines above.
If it is a new mask, you may need a different size or type to achieve a good fit. Please call our office and schedule an appointment with one of our fitting experts and we will work on finding the interface that best fits your facial structure.
