OSCAR data, Dreamstation vs AirSense 10 compare

[Phil7]

Howdy.  I've been on CPAP for 11 years (original Rx was for a static pressure of 13).   Ten years ago, I asked my MD for a CPAP script to escape the horrible medical supply company I was assigned to w/o choice.   I've been on my own for 10 years (in a void, my current MD and Insurance aren't aware I'm on CPAP).     Last night was my first night on an AirSense 10, after being on Dreamstations for around 5 years.   The CPAP dealer I uploaded the CPAP script to still insists the prescription is a "lifetime prescription".

I had never used OSCAR until a couple of weeks ago, where I really wasn't paying attention before the foam recall.   I was just curious if anyone sees anything I should be worried about (etc).    The images are the previous night on a Dreamstation, and last night which was my first night on an AirSense 10.   On both nights, I was sleeping with a Mirage II Nasal Pillow and my mouth taped.  

The OSCAR differences are interesting, where the Dreamstation is reporting different events and a higher AHI.  I'm trying to wrap my head around that.

Thanks!

Interesting improvement, side by side. Right off the bat, you were running FLEX on the DS1 but no EPR on the AS10. Seems that was a good thing. I'll let the experts come and offer more insight on next steps, but like me, it appears the AS10 is doing a much better job for you.

The statement that CPAP RX never needs to be adjusted is a typical moronic remark you will run into with some of these guys.

That is the difference in the treatment of your apnea with the 2 machines and it is what happens to most people when they switch.  The Resmed acts more quickly to stop the apnea.  What does drive the higher pressure are the Flow Limits on the Resmed.   Flow limits are apnea just like obstructive and Hypopnea events.  

We use EPR to help with flow limits and you don't seem to be using it.  So for tonight I would suggest you set your EPR to 3.  I would also move my min down to 10.  That should make your sleeping better and more comfortable.  We may need to move the min back up but I would suggest we try it a little lower for a day.

In OSCAR, ResMed and Respironics report various things in different forms. I think one example is flow limits. ResMed has it as a chart, Respironics as a left panel stat. It's just different ways to report the info.

Other differences between the machines are more important. Respironics are slower to respond to events for most, and Flex can't compete with ResMed's EPR. EPR is operating on known values of relief at cmH2O, same value type as therapy pressures. EPR also makes the AutoSet a limited to up to 3 PS BPAP.

Thanks.  I'm going to do some more reading and thinking tonight before bed.   I can't remember the details of what I read (or where) that lead me to turning off EPR when I first setup the machine.  I'll take a close look back at that.

So far, I feel a bit better today.   Sometimes I feel great during the day and get sleepy in the evening though.

Thanks!

EPR sometimes increases the centrals because with it you have LESS CO2 which drives centrals. If your centrals go up we can cut back until you get use hot the mew settings and then increase.
