machine life vs pressure
machine life vs pressure
I am under the assumption that a machine's lifespan is tied to the pressure it is run at....The higher the pressure, the harder the blower has to work.
I usually run at 9cmH20, and my machines are both still alive. My Airsense 10 is at around 3300hrs, My refurbed s9 I got around 4000hrs and now it has 10,700 hrs.
If you could write the numbers of hours on your machine when it died (or is still going) and your set pressure, that would be great....
Just curious, as I am on the lookout for another machine that does APAP. My prescribed machine is the Airsense 10 Elite, and it only does CPAP.

Re: machine life vs pressure
I never had a machine that died, but most machines should go 15,000 - 16,000 easily. (5-6 years). There are some that have gone 20,000+.

Re: machine life vs pressure
I am a long-time patient, (~35 Years) and have had only 1 machine actually die during use. It had about 15,000 hours of service when the blower completely died.

More important in life span of a XPAP is Quality, which we as users have no control over, and keeping leaks under control and filters clean, users with common sense, (not all that common) have the best luck using equipment.
The point of a XPAP is it's a tool to help keep you alive, not the other way around. I have 3 xpaps, same brand same age 16 years old, all working as well as the day they were bought, if our bodies did as well we all would be better off.

Use data to optimize your xPAP treatment!

Re: machine life vs pressure
Design of good machines would indicate that pressure would have little to no effect on longevity,
Abuse would have more effect--like exposure to smoke, soil, water, or (horrors!) ozone.

Re: machine life vs pressure
I just got an upgrade yesterday to an Airsense 10 from a Resmed S9 Escape with a pressure of 9.2 and 25,116 hours. It had no issues other than saying useful motor life exceeded. I got it in Dec 2011, yes I am a procrastinator as I have high deductibles.
Now I just got a S10 Autoset and they threw in a heated tube. I must say it is strange having the pressure go up and down. I am still trying to figure out what settings are best.
I feel as though I had a better sleep

People on this forum need to read the whole post.... or at least the full 1st line of the post.chunkyfrog wrote: ↑Wed Mar 10, 2021 3:55 pmNot an upgrade IMO.
Hope you or your insurance did not pay full new price--for a ten+ year old brick.
Those machines, even low hour, are worth about a Ben Franklin, not much more.
OK for emergency or travel--Autoset can be tightened up or even run in cpap mode.
Get the clinical manual free at apneaboard.com.
You still get data--but none with the escaped.
Upside: Nobody will steal the brick--unless they are dumb as the machine.
Re: machine life vs pressure
Curious, When did it start saying "useful life exceeded"?

Re: machine life vs pressure
I corrected my initial post I see the confusion, I got an Airsense 10 Autoset. The S9 Escape said useful life exceeded I think around the 21,000 mark I guess 8 years or so (guesstimating). Yes it is a brick, never had issues Since Dec 2011 with it. I was just afraid it would die at some point

Get the REAL manual--free from apneaboard.
You will love your Autoset.

My S9 Autoset has almost 30,000 hours and still works like the day I got it with zero hrs

Re: machine life vs pressure
I come from a long line of engineers. My sir name references Engineer on the Rhine.
Pressure and lifespan. Technically pressure can affect lifespan.
However, the pressures in these machines may feel high when breathing, but in the real world they are insignificant.
My Machine is set to 14 breath and 8 exhale. Quite high pressures.
I have one machine that has over 15500 hours. It was replaced because I changed insurance companies.
For liability, a new machine protects doctors and providers.
Next about pressure. The 14 means displacement of water 14 centimetres. That in actuality is VERY LOW.
I have several compressors. I use for spray paint, run Automotive tools, Fill tires etc.
These compressors can easily last 20 years and can often last 30 or more years if serviced
regularly. The Compressor can provide pressures of 150 PSI. Convert PSI to inches of water column
and you will see that CPAP/BiPap machines operate with VERY little pressure.
My BiPap pressures me at 14 Centimetres of water column. My Compressor
that does 150 PSI, which is equal to 10,541 Centimetres of water Column.
For Comparison:
14 Centimetres is slightly under 4 inches or 1/3 of a foot.
10,541 Centimetres is 345.8 Feet. 1/3 of a foot vs 345 Feet.
What wears out the machine fastest, is DIRT.
Keep the filters cleaned or replaced.
