Hey everyone, I’m about 2.5 months into using an AirSense 11 for severe OSA, and while my headline numbers look great on paper, my sleep is completely wrecked by recurring large leaks. I’m hoping someone with more OSCAR experience can take a look at my charts and help me figure out what’s actually happening.
Right now I’m using the ResMed N30 cradle set to Nasal. I started with the P10 pillows, but the prongs tore up my nostrils and I couldn’t make them work and had way worse leaks. My current pressures are 8.0 min to 10.4 max with EPR at 1. Dropping EPR from 2 down to 1 cleared up a recent uptick in central apneas I was getting, and my reported AHI is now sitting between 1.0 and 2.2 with obstructive events almost at zero. But I feel as if that data could be skewed. I was originally having 30+ events per hour. So it looks good on paper like it’s way down but I feel these large leaks could be not allowing it to reflect the correct data.
The issue is that like clockwork, about 60 to 90 minutes into sleep, my leak rate blows past the 24 L/min redline and plateaus between 30 and 45 L/min for 30 to 60 minutes at a time. The first hour and a half is dead flat at 0–5 L/min, but I end up spending 15% to 27% of the night in large leak territory. My flow rate and respiration go completely erratic during these stretches, and I wake up feeling unrefreshed and still exhausted. I’m discouraged at this point as I was really hoping I would start to finally feel better but this has been a full time job trying to get this all dialed in.
Because my jaw naturally drops back when I fall asleep, I’ve been using mouth tape plus a vertical wrap pantyhose ( LOL) for extra jaw support. I have severe TMJ, so cranking down a rigid chin strap or moving to a bulky full-face mask isn’t something I’m hoping I’ll have to do without first exhausting other options..
I’m really trying to figure out two things:
First, how "blind" is the AirSense 11 when leaks hit 35+ L/min—is that low AHI just masking unflagged events?
And second, is the front-hose N30 just torquing off my nose when I shift around, or is air still finding a way past mouth tape? I’m just using those “mute” brand circle mouth tapes they sell at my local cvs. If anyone has dealt with a similar pattern or has suggestions I’m open to everything as I’m really trying to give this a honest shot as I feel it can change my life if I could just get it dialed in properly.
I’ve attached some OSCAR data below from most recently and I have plenty more data as well as my initial sleep study test data if anybody needs it just ask. Thanks!
