One machine says I'm treated, another suggests I'm not - shawsg - 03-10-2024
Hello,
I have a strange situation.
I have two machines: an Airsense 10 and a Lowenstein Prismasmart.
According to the Airsense, my data is good, <1 AHI, pretty even breathing. I have both machines set to fixed cpap, same settings.
EPR 3 and Softpap 2, pressure @ 14.5
The Lowenstein data is terrible - it shows cheyne stokes @ 6% and the flow chart looks bad. it also shows no deep sleep. AHI is 8+
The data is like night and day. One suggests the therapy is working, the other, not so much.
If i didn't have the Lowenstein I'd think I was ok, but perhaps I'm not. Which should I trust and what should I do?
I subjectively feel the same until I look at the data
here's sleep HQ for the airsense: https://sleephq.com/public/8fba56f4-dca2-416d-8867-25876fb86547
and a PDF of oscar for the lowenstein enclosed.
thanks for your thoughts.

Which machine do you feel more rested on ? That’s the machine I would be using.

shawsg - A printout of the OSCAR Daily screen does not provide all the information we are looking for. Please carefully follow the steps below to produce the best screenshot for review.
Steps to organize the Daily screen and take a screenshot:
- Set the OSCAR to full screen.
- Make sure that your display is set to the Standard view, your graphs are in the default order, and all graphs are of the same size.
If not: - To reset the Default Graph Order: Go to (View > Reset Graphs > Standard)
- To reset Graph Heights: Go to (View > Reset Graphs Heights)
- Resize the Daily screen's left panel's width, so each channel parameter only uses one line and does not wrap the data. This allows more information to be displayed.
- Make sure you are at the top of the Daily screen and have not scrolled down. Also, make sure you are displaying the complete day's data, and not zoomed in to any specific time range. (Take a guess as to why we mention all this. . .)
- To take a screenshot of your Daily screen, select one of the following:
- For Windows or Linux: Use the F12 key
- For a Mac: While holding down the Fn key, press the F12 key.

The Lowenstein does not deliver EPR the same way as Resmed, and your flow limitation results show it. It would be more interesting to see zoomed images of the two devices at 2-3 minutes to get an idea of what your respiratory flow wave looks like. I'm pretty sure you will see a lot of flattened inspiratory peaks on the Lowenstein, but not the Resmed. There may be minor differences in the way the devices report events, but the flow rate wave form does not lie. I would retire the Lowenstein.

well I feel about the same on both, but one says I'm gonna die of heart disease in 10 years and the other one says I'll live a lot longer.
which do I heed?

Without closer examination of the flow rate, I'm guessing your perception of equal therapy may be off.
