New Member Lurker

I have been a long time lurker 3+ years. I know I can now both learn more and hopefully contribute to this forum by being an active member. I started on a APAP and then began using a auto BIPAP about a month ago, I also use a CMS50F and now ZEO. I have mostly been doing everything on my own as I didn't complete my first sleep study because my problems didn't start until halfway through the night and the tech said I would need to return so he would have enough time to do the titration, I explained that I already had an APAP and he felt I could probably start with that when I told him that I could do the settings myself. I have since been diagnosed with Cardiomyopathy (EF 45%) and am even more tired during the day. My AHI numbers have always been bad starting out over 20 and now with the auto BIPAP less than 10. I will attach some results when I have enough posts.

read all three pages, links at the bottom of the first two:

I added a few more items and so I hope the image is still useful. I thought the settings for the Dreamstation auto BIPAP would be the same as most I have read about but the PS min 0 max 8 seems a little different. Thanks for any help.

you can check with the 'preview' button to see what your post is going to look like, before you post it.

and if you follow the posting instructions, you can get it to look like it does above.

it's nice to see someone using the zeo, I like to invert the data (I think there's a check box on the export screen for the program, makes the it more intuitive for me, with light at top, and deep at the bottom, like so:



as to your chart, I'd say you need more epap to handle the apneas, and help with the hypos.

Anyone using the DreamStation auto BIPAP model 700? I have noticed when I import data from the SD card the description in the left column for the setting is PAP Mode: Auto Bi-Level (Variable PS) and this is what I have it set for. After importing O2 data from my CMS50D the setting shows to be PAP Mode: Fixed Bi-Level and then after importing ZEO it changes to PAP Mode: APAP (Variable). I am not sure if I am doing something wrong or if this a bug in SH v1.0.0-beta-2. I am a new member, still learning and using a MAC.

yes, that.

Welcome fellow Zeo user.

I don't have anything constructive to offer except to agree with PR a raise in EPAP may help.

I do have a question about your SPO2 line. It looks a little "fuzzy" with considerable seemingly rapid variation in min to max. Could it be the sensor connection? The pulse line looks OK, though. Is it meaningful? I don't know. See PR's for comparison.

BTW, I notice you slept on past turning off the machine (Zeo and Pulse-Ox still running). Not that it makes a huge difference and you might be aware, but this may mean your actual AHI is higher than the 7.67 reported. There are a couple ways SleepyHead can compute AHI selectable in Preferences. I think the default is total events/total session time. Total session time would be from the earliest start of any equipment session to the latest end of any equipment session, I think. You can turn the sessions for the CMS50 and Zeo off at the bottom of the left panel, Daily Detail, and see if it changes the AHI.

(nice job syncing to you both)

Thanks Jay,

I changed the scale for the graphs to reflect the minimum and maximum numbers and this why the lines are Fuzzy, but just wanted to see more detail. My AHI numbers are usually over 8 and so I was not as concerned about that as I am about all the events and because I always have a lot more after 3 to 4 hours I was curious what stage of sleep was in when they occurred.

Maybe, but the vertical scale isn't far from what I usually use. Here's one with the same Y axis spread of 11. However, the x axis is only about 7 hours vs your 10 which would tend to make mine look a little "smoother". To compensate, I made the chart about half the normal display width before snipping. As you can see, my variations seem to be up or down 1 or 2 percentage points at a time, while yours appear to move up and down 5 or more percentage points at a time. Again, I don't know if this is significant or not, or whether this is really only a matter of scale or artifacts. FWIW, I have seen one other similar appearing chart with rapid large swings in O2 and the owner complained of disturbed sleep and fatigue.
