Lately, I have been experiencing an comfortable chesty feeling after completing my nightly session.
It feels like my lungs are filled with air and is very unnatural.
My sleep doctor said this was how it supposed to be.
I don't think he has experienced a night of CPAP himself.
He did reduce the pressure from 12 over 8 to 11 over 6.
It takes until evening for the symptom to subside.
I reduced my pressure from 11 over 6 to 10 over 5. This helped the first night but it seems to be back.
My AHI is often less than 1 and I have no significant mask leakage.

The sensation is more like I have inhaled a lot of menthol - it's basically like I have a lot of cold air trapped in my lungs.
The sensation decreases during the day so that by evening I feel better but it's always there to some extent.
I recently spent 12 hours in the emergency department of a local hospital in an effort to get to the root of the problem but they found nothing wrong
I have had 3 chest X-rays in the last 2 months but still nothing wrong apparently.
I was told by another specialist I managed to see recently - he thought I might have a Hiatus hernia but it was just an opinion - no tests were ordered.
Does anybody on this forum have a condition similar to mine?
I would be interested to know if anybody feels normal afer a night of CPAP or are there always some lingering effects on the lungs?
Is your machine in "S" (Synchronized to your natural breathing, with fixed IPAP and fixed EPAP) therapy mode or "VAuto" (synchronized to your natural breathing, with fixed Pressure Support but auto-adjusting pressure) therapy mode?
If in S therapy mode, regarding having lowered your pressure settings to "10 over 5" does this mean IPAP is 10 and EPAP is 5?
If in S therapy mode, if your AHI is still low, you might want to consider lowering IPAP a little more, like to 9 or 8, while keeping EPAP unchanged.
When we have an overnight lab titration, we are usually asked to sleep at least part of the time on our back. This is because being flat on our back is usually the worst case for obstructive sleep apnea. But if we make sure we are never sleeping on our back, we may be able to use far less pressure than was determined during our overnight titration.
The data from your machine (for example, AHI and Flow Limitation) would likely show whether the pressure has been lowered too far to adequately prevent obstructive events.
Lowering IPAP while keeping EPAP unchanged may make it a little less easy to inhale and may occasionally increase Flow Limitation, but may also reduce stress on your lungs.
