How reliable are your machines?

[tarpatel]

For those of you who have used the machines for years: how reliable are these machines?

[PaulKTF]

Solid as a rock, but it's always good to have a backup machine just in case.

Machine malfunctions are rarely the cause of any trouble, especially if they're from the big two' (Resmed, Respironics) or handful of other popular machines used by most even internationally. Their function is pretty simple and even if something were to go wrong, replacement (if valid) is usually very fast from reputable dealers, but having back-up machines (either older ones, travel ones or secondaries of our everyday ones is recommended for when either ours are at the end of their lives, or forgotten in hotels (or anywhere else), or do have minor glitches for any reason. Fixing those is usually fast and inexpensive (especially through acbio.com if otherwise out of warranty).

[D.H.]

I've had four machines, and only one of them actual broke to the point of immediate unusability. That was an Everest-II machine from AEIO-Med. The cord on the power supply (the part that connects to the unit or battery pack) burned out and became unconnectable and also ruined the socket in the battery pack. That company went out of business in 2009, due to a fire in heir factory in China.


Fortunately, I had my old and trusty (and very large) F&P HC-233 as a backup, so I did not miss a night.

I have had a Resmed S9 for over 4 years, no notable issues, and I have traveled with it a fair amount.

Getting a new dedicated smaller travel CPAP and will also have this as my backup should my old S9 ever fail. I could get a new Resmed for no cost though insurance but see no need to do so since it works fine.

Hi tarpatel,

You may or may not be familiar with the term engineers use – 'mean-time-to-failure' – 'mean' meaning 'average', 'the statistical mean'.

AFAIK, the MTF for Philips Respironics machines is 10,000 hours. I don't have a hard number for ResMed machines, but I imagine their MTF is in the same ballpark.

I thought these machines had about a 5 year lifespan.

No.

Typically the timeframe for insurance carrier to replace a machine is 5 years.

Arizona Willie has an S9 with over 25,000 run hours...that's about 10 years.

I wonder why Resmed is telling us it’s typically 5 years?

My S9 has 21,000 hours so far.

Because ResMed makes money by selling machines.

Most leased car are replaced at 3 years, I would not interpret that to mean the average life span of a car is 3 years.

thank you for the education, rick. not being an engineer, this was new to me.

[remstarcpap]

As a self-paid cpap user, it's pretty clear that most machines will basically last a very very long time, as I have several S9's close to 20,000 hours. The only "failures" I have had were a pin broke off on the power supply, so I needed a new one, and one Climateline hose failed to heat after perhaps a few years of use. I suspect that like my car, the desire to upgrade to something better will happen before my machines die.

Of course this only applies to machines from Resmed and Respironics, and probably not to tiny travel machines.

Probably not so much THEIR travel machines, either.

Being ridiculously wealthy, I prefer to replace my machines before they fail.
My PRS 960 ASV has less than 13,000 hours, I replaced it with an almost new Resmed AirCurve 10 ASV. I am keeping the old one as a backup, unless someone makes me a ridiculously generous offer.
I did sell my S9 Autoset after 3 years, when I moved on to ASV.
I also like newer tech.
For those who question my wealth I have some great bridges I will sell cheap.
