Sorry. You can't do this in baby steps. You need to do the following and really quickly:
1. Get educated in CPAP/APAP machines and all things CPAP/APAP. There's plenty online.
2. Get the best CPAP/APAP machine you can afford along with a really good humidifier and accessories like a hose cover, hose support, etc.
3. Get that machine set up to the pressure settings that you need (my doc started me at 4 and then said "ooops I meant 9" so I set my APAP to 7 to 13 cm. And I like it. It adjust automatically to my needs.
4. Get a mask that FITS and that is COMFY. I highly recommend the Mirage Activa LT... as far as fit is concerned I have a large face and am using a size not widely advertised. LARGE WIDE... it makes a great seal as it sits widely on my face and the wider the mask the more stable it will be. If it will make a good seal (and the machine that I use will tell me at the start of use and alarm if the seal breaks). For goodness sake do NOT put up with a poorly fitting mask for what they cost.
5. MOST IMPORTANTLY!
YOU NEED TO BE USING THAT MACHINE AS INTENDED EVERY SINGLE MINUTE THAT YOU ARE IN A POSITION TO FALL ASLEEP. PERIOD.
FORGET STARTING SLOWLY AND SUCH.
IF YOU NEED THE MACHINE AND ARE NOT USING IT YOUR BLOOD PRESSURE WILL RISE TO THE POINT WHERE YOU ARE GOING TO SPLIT YOUR AORTA, POP AN ANEURISM, HAVE A STROKE OR A HEART ATTACK. 'He/She died PEACEFULLY in their sleep, poor thing'.
I cannot overemphasize sufficiently... if you have sleep apnea or any other obstructive issues or lack of air intake issues you need to have that machine running and the mask on at all times that you may fall asleep or you are begging to have an 'event'.... that just might kill you.
I don't think it can be any more clear. Read the articles and white papers if you don't trust my opinion but I assure you that I have nothing to gain by suggesting this to you.
A good machine, good mask, you will get used to it in a jiffy and if you don't that's a shame... you still need to be wearing the thing. Your life just may depend on it.
Fall colours. One of God's gifts. Life is fragile and short, savour every moment no matter what your problems may be. These stunning fall colours from my first outing after surviving a month on life support due to H1N1.
