SH Data Interpretation Advice Needed Pls
Hi, I'm new to the forum having being diagnosed with OSA about a month ago and receiving my DreamStation on 27th Jan. After 10 nights I had my first recall and my PR Wisp mask was changed for a PR Dreamwear which I am very happy with. My starting pressure was pushed from 4.5 up to 5 and I have stopped the 'gasping for air' issues I was having during the ramp phase.
I'm female, 52 overweight and on the slow NHS bariatric pathway hoping for surgery at some point. In the meantime here I am importing data into Sleepyhead and playing with chart sizes ready to ask for assistance.
These are my 'best' two nights in terms of I have woken up feeling more refreshed and alert than I have for a couple of years, so I thought I would post them as ask for an interpretation. What is happening during the night, are my CA, OA, H's too high? How can I improve each ?

Your minimum setting of 5 cm pressure may be insufficient for you. Some folks find they feel like they can't get enough air at a setting of 5.
You seem to stay below a maximum pressure of 10 cm. To me that suggests a maximum of 15 could be lowered to 10.
If you sleep on your back, sleeping on your side might reduce some of the obstructive hypopneas and apneas.

G'day FancyPants.
An AHI under 5 is regarded as "treated" but most of us feel better if we can get it down closer to zero. (Regularly achieving zero is not a realistic target, however).
In your case you are achieving "treated" results, but still with quite a few hypopneas. I'd be inclined to bump your minimum pressure up to 6 and see how that goes. The Philips machines take a fairly conservative approach to increasing pressure, so if your starting pressure is too low a lot of events can occur before the pressure gets up to therapeutic levels. Starting with a higher minimum allows the machine to effectively respond faster, and should also reduce any precursor events such as snoring or flow limitations.

After reading your advice guys I am changing my machine to start at 6 to try and reduce the hypopnea count which in turn should reduce my AHI. Thanks
