Dreamstation 1 APAP Function Not Working?

Dreamstation 1 APAP Function Not Working?
My refurbished Dreamstation 1 APAP function not working?  The refurbished machine sent back to me by Philips does not seem to be regulating the air pressure.  When turned on to APAP and set on a range of 10 - 17 psi it only stays at 10 psi or whatever the low psi setting is and does not regulate.  Never had an issue with my other Dreamstation 1 machine and think I have everything set up correctly.
Any suggestions?

It would not raise in pressure unless you are having events...  I would suggest you use oscar (free download  at the top of the site) and post a daily view of a normal night for you.  Someone here that is experienced with your machine will be able to help.

        I do use OSCAR.  Here are two brief screen shots.

I am actually having a similar issue with my refurbished Dreamstation 1 and I have been wondering if I'm just interpreting the charts wrong or if there is an issue with the machine. 

I have an event, the pressure spikes for about 30s (looks like literal triangles on the Oscar chart) and then the machine immediately goes back down to the minimum setting. Then I have another event a minute later and the pressure spikes and then quickly goes back down to minimum, etc etc.

I hope someone with more experience reading the Oscar charts can help us make heads or tails of this.

I called my DME but they're useless now that they get their money from Medicare. I don't have any problem with my Airsense 10 on APAP.  I think I'll try the Dreamstation on fixed pressure for a night....I only use it for when I travel so I haven't experimented much.  Wonder if there is a Philips tech support?
