Hypopnea Increased after lowering EPR?

[fdw]

Hello All

I decided to lower EPR from 3 to 1 figuring it would help with excessive CO2 intake take which may be affecting my heart rhythm (AFIB), now I've noticed that Hypopnea's have really ruled. I also changed my min and max pressures from 12-16 to 10-14.

Anyone care to comment?

Thanks

Why do you think you're inhaling CO2 instead of it;s going out of the vents?

And do you kmow that back sleeping causes more events like hypops?

Blood test results indicated higher than normal levels CO2

I only sleep on my side, never on my back

The lowering of the minimum to 10 from 12 is likely the cause of the slight increase in hyponeas.
Could also simply be a normal nightly variance.

Do you suppose I should return to my previous pressures?

Do you suppose I should return to my previous pressures?

If it were me I would continue with current new settings for a week or so and see if any trends or patterns develop.
I don't ever change anything based on one night's results.

The slight increase right now...still well within acceptable range and it very well could just be normal nightly variance.
I had a night last summer where my AHI was 9.4...normally it runs around 1.0 or a little less. It was just an off night fluke.

Don't forget to factor in how you sleep or feel into your choice.

Higher EPR blows off more CO2 though, because it mimics bi-level pressure support. Did your doctor mention and discuss your CO2 levels with you? Or did you just look at the results yourself. Need some more information here.

As raisedfist says, higher EPR will tend to wash out more CO2.

I'm curious: when you lowered your EPR, did your flow limitations increase?

In any event, Pugsy has the best advice for you. Give the experiment a fair run for its money before you try to assess the results.
