I would get a proper apnea test from a medical provider either at home or in a hospital overnight.
Many/most of the "continuous" oximeters on Amazon etc that measure your levels while asleep give unreliable readings, according to the reviews I have read.
I bought one and tried wearing it throughout the day as a test. It would fluctuate wildly at times even though I was fully awake and the reading on my regular pulse oximeter was normal. The sensor would slip and light would get in unless I bound it too tight for comfort. Fortunately, I was able to get a partial refund. I don't think the oximeter functions on smart watches are much better, other than as a rough guide.
If anyone knows of a reliable overnight oximeter, I would be interested to find out.
Ok that explains it. Thank you.
You mentioned CA events should not cause pressure to increase. So what caused the pressure to increase? I had zero OAs and zero hypopneas. There were no major mask leaks. However, I noticed the flow limit rose around the time the mask pressure picked up. Why would the flow limit rise if I had zero OAs and zero hypopneas?
Yes, that is what I am worried about. I guess I won't find out until I try. Was just wondering if people with deviated septums can give me any advice or share their experiences. Nasal sprays didn't help much. I am hesitant about surgery.
I read about the nasal cycle. In healthy people, the turbinates on one side of the nose naturally take turns swelling up to cause congestion for three to six hours on one side, in order to give the cilla in that nostril a break and prevent them from drying out. Then the same thing happens on the other side.
When I have a blocked nose, I am fine for a few hours when the left side is on duty, but start breathing via my mouth when it is the right side's turn.
You said the nasal mask seems to keep at least one passage open.
I wonder if the body will let the off-duty nostril stay open.
I hope so, and hopefully the humidifier would protect the cilla while they work overtime.
Thanks, I should have mentioned that I live in Japan, so this is a Japanese ResMed model.
Oscar recognizes it as a "Resmed S9 Sleep Mate 10 Auto in APAP mode".
The vendor told me to use the English manual for AirSense 10, as the machine is almost identical to that.
I tried EPR at full-time, level 2, but I felt like it was hurrying my breathing, not supporting it.
Hi, I have a deviated septum.
The passage on the right side is significantly narrower than that on my left side.
I find reflux causes mucous production in the nose which makes me blocked on both sides.
If I can avoid this by not over eating late in the evening, I can breathe to some degree through my right nostril, while the left is fine.
Have you heard of people with deviated septums that have succeeded with nasal CPAP masks?
I have yet to attempt a full night with a nasal mask and am a bit hesitant as I don't want to wake up with an aching, dry throat.
did you ever find a solution?
I used the Wellvue O2 Ring oximeter - the one with the thumb sensor and main device on your wrist. I found it inaccurate.
Thanks I am using a Sleepmate 10 Auto in APAP mode. I turned EPR off, as I found it easier to breathe without it. At the moment, I am only testing the machine in the afternoon for short periods. I have a full mask and a two nasal masks and am still trying to work out which is best.
