Yesterday I was committed to continue with the CPAP, however as soon as it reached the evening my headache was so strong that I had to take another paracetamol to calm it down.

I told myself that if I had another day like the previous two, I was going to colapse from the fatigue so I decided not to use CPAP, and my deep sleep immediately doubled from 20 minutes to almost 50.

I dont know why, but I can 100% say that the CPAP is currently affecting my deepsleep. I am confused because this has not happened before.

I, like you, had 0.00 % deep sleep on my polysomnography.  It was such a new experience for me, I think that was the reason (1st time ever using pap).  I got a smartwatch and it shows I am getting some deep sleep at night, but less than normal.  And then, the validity of smart watches comes into question (how accurate are they really?  Most likely not 100%).  

You may be very sensitive to air pressures and you may have a more sympathetic nervous system tone (more wired and more alert and more sensitive).  People who can get into parasympathetic mode easily ("rest and digest") can usually tolerate pap better and enter deep sleep more quickly and spend more time in deep sleep.  It may take some training (adapting to pap therapy over time) to convert.  You might even try lowering your pressures a bit so you can more easily adapt to them.  And later increase them as your tolerance to them increases.  

Just some food for thought.

Room air oxygen percentage is around 21%. Cpap air is probably around 21% or so also - since the air coming through the intake is room air.   So, if the air you breathed was mixed with an oxygen concentrator for example, the percentage of oxygen in the air would increase.  If you traveled to a place of high altitude, the air there usually has a lower percentage of oxygen than at sea level or below.  

2.  It was a very novel experience for me as well.  You can keep the data from your watch to show to your Dr. in the future if you ever need to do so. 

3. It took me a long time to get used to pap/vent therapy.  I feel your pain.  


You can lower your pressures a little bit.  Lower your epap max and ipap max by 1.0 or so.  You can even lower them both by 2 if that doesn't work.  Keep going until you can sleep with it.  Your OSCAR may look horrible, but you may get used to it so you can increase pressures later. 

Sleeprider would have had you optimized very quickly already if you could have tolerated your therapy.

It you feel like the machine is trying to get you to breathe too quickly, you can reduce the trigger (from high to medium for example).  Or very high down to high ect.  

If you feel like the machine is too slow for your breathing and you can't get enough air and feel like you are suffocating, then increase the "trigger" setting (from medium to high) or high to very high, etc.
