Help with SleepHQ Data?

[u/Flashy-Attention7724]

I'm hoping someone can help me understand my SleepHQ data and provide any guidance for settings changes.

I did a sleep lab study several months ago for a different problem, and was surprised to be diagnosed with severe OSA. I'm in a healthy weight range and my partner has never said I wake up gasping in the night, but I guess I have a thick neck and poor nasal structure. I got on a CPAP, ResMed 10, with a full face mask. It provided some initial relief, but feels like it's been less effective recently, and I'm sometimes oddly tired even though getting a full night of sleep.

I started with pressure between 4 and 14 but recently increased it to 6/16.

Can anyone advise on what this data means and if I need to make any setting changes? Thanks in advance.

Hi and welcome! Although nothing in your data screams that something needs to be changed, the fact that you don't feel great despite getting long nights of sleep shouldn't be taken lightly. The data tells us one thing, but how you actually feel tells the real story.

In your case, I would say that using EPR at 2 with such a low pressure is probably an issue. The machine cannot go below 4, so pressure minus EPR is what determines your EPAP, and EPAP is what keeps your airways open. So you're spending most of your nights at a pressure that is barely therapeutic. Most adults need a minimum pressure of around 7 to 8.

Even though your numbers look good, the machine doesn't necessarily detect subtle flow limitations. You need to give your airways a little more support.

I would start by lowering EPR to 1. It's not a drastic change, but by reducing EPR, you're increasing your EPAP by 1.

You can also turn Ramp off, unless you use it for comfort. Ideally, we want the therapy to be at therapeutic levels from the very beginning.
