If I use the setting that turns the machine on automatically when you put on mask, I sometimes find that the machine turns itself on arbitrarily during the day and runs unattended. I’ve carefully turned the machine off manually in the morning and found the machine running when I went to bed. The water chamber was very hot. It stopped turning itself off as well when I removed mask in morning which it used to do.

If I turn off the auto on feature, the machine stops turning on by itself when not in use. Unplugging and resetting the machine did not fix .

This is my second resmed machine that seemed to have problems with the auto set feature.
Oddly enough, my respiratory supply company said my sleep reports looked normal even without me using the machine so I have no idea what these reports capture.

Anyone else with this experience or recommendation for a reliable machine?

I use the AirSense 10 AutoSet machine with the SmartStart enabled, and have never known the machine to start by itself. My wife uses the ResMed S9 with the same feature turned on and no issues with it either. I turn my machine off manually in the morning, but my wife lets it turn off automatically. it seems to work. I have heard of some having issues with the machine not turning off. That I think can be related to the using a very low set pressure. The flow switch that turns the machine off must not see enough flow to trigger it. My thoughts would be that you probably have a defective machine. It should not just start all by itself. Is it still under warranty? You may want to try going that route. Here is a link to a technical manual for the A10. There may be some troubleshooting help in there that I have not thought of. As far as reliability goes my wife has been using the S9 for about 4 years, and myself the A10 for about 2 years. No problems experienced with the machines, but my wife did have a problem with a DC to DC adapter we bought for camping. It would trip out during the night. ResMed supplied three of them before I gave up getting it to work. It would work with the humidifier and heated hose turned off, but would trip out when they were turned on. I suspect the design was flawed. The auto cutout was set too low. I use the same type of adapter with my A10 and do not have the problem even with the heated hose and humidifier turned on. Other than that, the machines have worked well.

If you go with another machine brand, I would suggest the Phillips DreamStation Auto. They tend to be a little less expensive. The only thing I don't really like about them is that they do not allow you to set the Flex (like ResMed's EPR) so it is on during the ramp, and off during sleep. I also like the auto ramp feature on the ResMed. The DreamStation has something similar, but not as good in my opinion. Here is a link to a DreamStation technical manual. It gives you some idea of the features it has. The manual however can be somewhat confusing as it covers the whole range of DreamStation manuals, so you have to pick out what applies to the Auto version. One advantage of the DreamStation is that it uses 12 volts DC instead of the 24 volts that ResMed uses. So it can run with a simple power cord from a 12 volt battery without any expensive DC to DC converter.

The machine I would suggest you avoid is the Fisher & Paykel Icon+. I used one during my trial period and did not like it. The data from it cannot be read by SleepyHead, although OSCAR may have been updated to read it. It also does not distinguish between obstructive and central apnea. I think that is a significant limitation especially if you suffer from central apnea events. The machine should be smart enough not to increase pressure with a central event, but increase if for a obstructive event. The F&P can't do that.

Hope that helps some,

I don't know if this would trigger it or not, do you lay your mask near any fan or humidifier where air could be forced into the tubing? That would start the machine but it should shut off when it realizes there is no resistance to the pressure.

I had the opposite problem, I have auto on/off during the night my machine would turn off.

I have a Fisher and Paykel machine and it works well for what I want it to do.

My first Remed machine turned itself off a few times during the night. It was just one of a number of idiosyncrasies that eventually led to that machine being casually discarded with no follow up and no accountability. Resmed Problems

For expensive machines that are essentially medical life support devices the seeming lack of safety standards and regulations is really puzzling.

When I called the sleep center because of my problem of my machine turning off the tech said they had problems with Resmed when the auto on/off was turned on.

My first machine was an F&P, the thing I liked about it was it had a clock and an alarm in it. I don't understand why all CPAP machines don't have a clock display. It has a clock in it, it has a display, it sits on the night stand. It takes up an outlet. Having a clock on the display would eliminate nightstand clutter.
