Hi Birdy. You are so going to love your new life when you get started with your cpap machine and become a former smoker. Good job on making those committments to yourself.
I too was advised by my docs to quit smoking for a long time. Remember when dirt was invented? Yeah, that's about how long ago it has been. I did become an ex-smoker about 10 years ago, which as about 5 years too late. So I have what is lovingly referred to as "severe emphysema." That's what the docs call it. I'm not sure I accept that. But the point is it will be so much more convenient for you to bite that bullet and become a former smoker before you get to that point rather than after. A couple of things: Never tell yourself you are "quitting smoking." That just reinforces Mrs. Brain things that at any time you can suck up another cigarette and all will be back to "normal." When you put down the old match book, tell yourself that you are a non-smoker. It's not a matter of quitting, it's a matter of been there- done that. You quit. You are a non smoker.
The other secret I have is keep a nice supply of "snacks" to nibble on. I used jelly beans. Yep, I know, too much sugar, blah blah blah...... But they worked me. Celery sure would not have been an option. The only thing is buy good quality jelly beans because the cheap ones have to much wax in them and you'll not be able to craxxxxxxx for a month.
Enjoy your start to the new you. You will be very pleased with the results.
From a medical therapy perspective, the titration is important to confirm that the use of CPAP will reduce the number of apneas/hypopnea events in you, and is therefore medically indicated (required) as a solution to the problem. If for some reason, increasing pressure in your airway does not reduce hypopneas, then giving you a CPAP would be the wrong thing to do.
Therefore a titration study does 2 things:
1. Confirm CPAP or other PAP is a valid solution to the bad sleep and O2 desaturation problems; and
2. Figure out the lower and upper limits needed at various stages of sleep.
If things get really interesting during the titration study, then they will determine if you need a Bilevel or ventilator or some other more technically complex machine.
To us patients, we don't see all the effort and analysis that goes into titration study. They are looking for the simplest solution to our sleep/breathing problems. However, some patients need more complex solutions. Based on those results and other co-existing conditions in the patient, the doctor will make a recommended pressure and machine prescription in order to achieve the best outcome for the patient.
