Dreamstation Blows constantly
#1
Dreamstation Blows constantly
I have been a CPAP user since 2003. My pressure is currently set to 11.0. I own two dreamstation 1 machines and both now have the same problem. When started they blow air continuously until I exhale violently. At that point the machine begins to “ breath” with me supporting my inhaling and easing off when I exhale. 

This is great until I take a deep breath at which point it just blows air continuously until I exhale violently again. Obviously this has driven me to park both machines and trying to get them repaired with the recall active is, I understand, not possible. 

Any suggestions are welcome as I have tried every combination in the patient mode and therapy mode I can think of.

First guess is that your mask vent is plugged/bad.
How old is the mask (including elbow where the vent is) ?
Which mask do you use ?

Thanks for your feedback. I had the same initial thought given that it is two machines. I replaced the mask valve and elbow assembly. In addition, I have collected several backup masks over the years. Both machines behave the same with all of them. Very strange and Phillips has been no help at all.

Did you happen to take them apart to remove the recalled foam in the airbox ?

No. I’ve never opened either machine. The strangest thing about this is I removed the SD card from the old one that had stopped working. I pressed the newer one into service and it worked great for two days. Then since it didn’t have an SD card I zeroed out the card and transferred it to the newer machine. This is when the problem started. Unfortunately there is no factory reset on this machine.

Try rebooting the old fashioned way. Unplug wait a couple of minutes and plug it back in.

Just to be sure, are you aware that your machines are part of a giant recall by Philips Respironics? If not, you can find loads about it elsewhere on this site.

I’ve tried the reboot procedure resulting in no change on either machine.  I’m having trouble understanding the response from Phillips. JUST DON’T USE IT. This just isn’t an option and they don’t seam to care. Very strange customer support response in my opinion.

" .. the response from Phillips. JUST DON’T USE IT."

That might be an acknowledgement to the recall. Did you already register the machine(s) for the recall ?

Has your local equipment supplier taken a look at the machine ?  They might have something to measure the pressure/flow to verify the malfunction, or might have an idea of what to try.

Both machines are registered for the recall. When I took them to my local supplier they recommended not sending them to Respironics as they impound any dreamstations until they can apply the airway fix or replace them. I am considering buying a new Resmed but the price bugs me.
