Hi, I have been living with sleep apnea since 1994. I am currently using my 2nd CPAP machine which was prescribed in 2004. A sleep study was done to determine the amount of pressure to set the machine at. I had my 1st macine for 10 years and my current machine is now about 6 years old. Is this a normal life span for these machines?

    I got my first cpap about January of 2007 and it is still working well. It is a ResMed S8. I have now been using the ResMed S9 for about two months. The S8 reminded me what it was like to sleep at night. Now with the new S9 I am having my nights of sleep enhanced. I suppose the machines are made to last for quite a while since ones medical condition is given such high priority.

    My first machine lasted around 7 years and the only thing wrong was the on /off switch. Since it was older and out of warranty it could not be fixed. The machines usually have a 1 yr warranty with the option to buy a extended warranty. The catch is the longest warranty is about 3 years and the machine lasts about 5 to 7 years. The bottom line they want you to buy a new machine not keep the old one running.

    Hello,

    It seems that different doctors have different ideas on how often a sleep study should be repeated. My sleep specialist recommends every two years if all is going well. He says that if you notice a return of symptoms like daytime sleepiness, have major health changes, weight loss, gain, etc. it is good to repeat more often.

    Some of the new CPAP machines are data-capable and have software to monitor your therapy. If your machine is one of these, you would, in effect, be getting a sleep study every night.

    This is all well and good. However, at least two things typically missing from the data one collects at home are the EEG (measures consciousness/sleep state) and the pulse-oximeter measuring O2 saturation. Those are things that are very important to know.

    The life span that you mentioned for machines is what I have always been told. I read online where one Sleep Specialist said that anything over 6 years is way too long to keep a machine. He said that even with proper care of the machine and filters, the machine can become contaminated. Some fine dust does manage to find its way in, as does some humidity from our heated humidifiers.

    The real answer to this question can only be answered as to how often your insurance company will pay to replace one.

    It sure would be nice if we could all be be able to replace machines to benefit from the advances in technology that continually make them smaller, quieter, and have advanced features for comfort.

    Hope this helps answer your questions.

    The insurance companies will pay for a new sleep study every year and if you want to know what is going on with your sleep in a regular basis then may l suggest the use of an autopap from the local cardiopulmonary department at your local hospital. I am working with a Respiratory therapist who is also a friend. He provides me great new info about new masks and info on the web to read. And your insurance will pay for a new machine every 5 years.
