"Your home sleep test did use pulse ox, but it did not use pulse ox to measure your AHI . It *likely* used nasal cannula to measure air flow and a belt to measure respiratory effort. It then used that data to determine AHI and Obstructive/Centrals It did *NOT* use pulse ox to measure AHI." My home s...

My home sleep study used pulse ox to diagnose sleep apnea and give an AHI. There was definitely no flow rate. and the way you superimposed the bar graph doesn't actually cover the whole hour on the Oscar graph - I'm not saying that the events are the same # just they occur in same place at least the...

Also I do not know if this is just normal but it's clear most of the events are happening during REM sleep which I read is when the airway muscles are more relaxed.

what do the numbers in paretheses next to each time mean (under the Events/ Central apneas)

This is the zoom in of one part of the night flow rate

“Go here and watch the videos and learn how to zoom in and evaluate the flow rate (breaths) for asleep vs arousal flow rate. If awake/arousal related flagging then we worry more about sleep quality itself as in why the poor sleep.” Pugsy, where do I go to watch the videos? Actually I do know how to ...

https://imgur.com/a/m2OXAro This is the report from the sleepon ring It has seemed to be fairly accurate in the past, but is obviously reporting much higher # of events during 1-2 and 4-5 am than the machine is reporting. But the ring is using pulse ox data to measure. By matching I meant the events...

So one other thing that kind of worries me is that I have a ring that gives me AHI number which was much higher (19) and while it may not be accurate, it does match the times when the machine says I had events. So I’m wondering if the machine catches all of them? I’ll put it in Imgur and post.

Also the flow limitations are in the 3rd chart at top - theyare cut off at the top but they didn’t go higher than any of those lines… But next time I will do the ones below if they will all fit. I tried to change the size of the graphs using the file menu but I couldn’t figure it out. So flow rate i...

no idea what eg flow limitation means (tidal volume was another one) IMO, you are trying to run before you can walk. Priorities at this point should be using the CPAP all night, keeping the mask leak level within a good range, achieving an acceptable AHI, and getting sufficient restful sleep. (What...

Did you have very many wake ups during the night last night....or do you feel that you slept solidly for most of the night? Do you remember waking and noticing a leak? Would intermittently untaping my mouth during the night, and breathing through it maybe cause the leaks? The machine claims my mask...

The priority is to get you accustomed to sleeping with the device. If your chart was from someone who was accustomed to CPAP, I would increase the minimum pressure a bit to flatten the pressure trace, and decrease EPR by one. What does ‘pressure trace’ mean? I can increase the min pressure to 10 I ...

The second and third graphs aren't of much value. I would narrow the traces and include the flow limitation trace

I don’t know what narrowing the traces means? Sorry. I am lucky I can figure out the Imgur stuff at all !

Did you have very many wake ups during the night last night....or do you feel that you slept solidly for most of the night? Do you remember waking and noticing a leak? I did not wake up at all or remember waking up once I fell asleep. I wore the mask earlier in the day to get accustomed but didn’t ...

Here are my graphs from last night, I kept mask on all night (used new nasal N20 airfit) and cervical brace. AHI is better but mostly central? Do not feel rested waking up. Any input appreciated, thanks.

Can anyone tell me how to view the pie chart on Oscar? It's never shown up in my view. I am trying to read the Oscar info from sleep apnea board (is that a different forum?) but it's too detailed andI have no idea what eg flow limitation means and when I tried to read about it I couldnt really under...
