ResMed Autosense smart start not working

[gary1]

Hello everyone.  


New here.  I completed a one month trial using a machine.  My Sleep Apnea was 10 per hour so considered mild as I was told.
Anyway I am using the DreamWear Nasal CPAP Mask.  I used their ResMed Autosense 10 for one month and used the Smart Start
feature where after you removed the mask it would shut off in a few seconds.  Nice feature.  So I go ahead and purchase my own machine
and had everything set up like the other one I did my trial with.  The first morning when I removed my mask, the unit didn't shut off.  I thought it was just a fluke.
It did the same thing the other 3 or 4 days.  Unit would not shut off and just kept blowing out a strong air flow.  The respiratory person I told this asked their
ResMed rep and the answer they gave her was the mask I am using has a too low of air flow and the machine doesn't sense it when I remove it.
But it worked flawlessly with the other same exact machine for a month.  So I am asking anyone here if there is any truth to their answer or do I have a defective machine that would either need a reset, or an update or is it defective???  Thank you for your thoughts and suggestions in advance.

Is smartstart turned on in the clinical menu?

Yes, make sure the smart start feature is turned on. 

I wasn't happy about how long it took for the air to stop once I uncoupled my mask from the air hose. So.....when I need to visit the restroom at night (which can be numerous times), I just reach over and turn the machine off. The air flow stops immediately. 

Once back in bed, I reattach the hose to my mask, take a breath, and I'm back in business.

I use my machine in the same way as I have a nasal mask, it’s documented in the manual that with a nasal mask smart start won’t work.


I use the off button to turn off the machine and smart start to start it

smartstart works fine to start the machine with nasal pillows. I always stop therapy with the button so don't know if the stop function works consistently with pillows. it did the few times I tried it. however, as I recall the manual indicates a pressure under which it won't work, 7cmw maybe?
