I didn't sleep during the study, because it was held at night, and I sleep during the day.

Eight hours of lying awake on a bed with a full face mask on (and strapped tight) was a charming introduction to sleep medicine.

Regardless, the very credentialed sleep lab doc said: "No problem! (switching to a mexican accent) Sleep study? We don't need no stinkin' sleep study!"

He prescribed a Respironics M Series Auto CPAP Machine with C-Flex. Full face mask. Default limits on pressure (4 to 20?).

................

The first day I woke up gasping because I couldn't exhale.

Called the sleep doc, he said: "No problem!" I had to visit them so they could set the C-Flex (which was off) to 3.

The next day, same result. Recently, I've had an apnea that lasted 24 seconds and it didn't wake me, so I can only guess how long I was without oxygen during those two events.

Two wake-ups like that was enough for me. I returned the unit. My sleep doc looked very hurt.


-------------------

Went to another sleep lab, titrated to 10.4

Used a ResMed CPAP the next day, and 10.4 was fantastic.

I'm on ResMed auto-pap now, but 10.4 was an important floor to establish. Gradually increased the upper to limit to 14.5

--------------------

Finding the right mask was another long and frustrating story, for another thread.


But if you have the insurance, I'd always recommend a sleep study.

Abstract
Background: The increasing recognition of obstructive sleep apnea and demand for polysomnography has created a need for home sleep testing (HST) utilizing unattended diagnostic and titration studies. While these studies increase access to care and reduce cost, the limited interaction with sleep laboratories may negatively affect positive airway pressure (PAP) adherence. We sought to determine the difference in PAP use between HST and traditional in-lab studies.

Methods: Observational cohort study of 210 OSA patients classified into three equal groups. Following pre-established guidelines, group 1 underwent unattended, type III home diagnostic and unattended home auto-adjustable positive airway pressure (APAP) titrations; Group 2 underwent in-laboratory, type I diagnostic and CPAP titration studies; Group 3 underwent type I diagnostic and APAP titration studies. Group 1 was primarily managed and educated in a primary-care clinic, while groups 2 and 3 received extensive education in an academic Sleep Medicine Center. Objective measures of PAP use during the first 4-6 weeks of therapy were compared between groups.

Results: Type of study and location of care did not affect PAP adherence. PAP was used for 70%, 73%, and 72% of nights in Groups 1, 2 and 3, respectively (p=0.94). Mean hours of nightly use (4.4±2.0, 4.7±1.5, and 4.6±1.5, hours, p=0.98) was also similar. Regular use was observed in 54%, 51%, and 50% of subjects (p=0.84). Discontinuation rates were similar between groups.

Conclusions: PAP usage did not differ between those undergoing HST versus in-lab studies. HST offers a more accessible and cost-effective alternative without compromising therapeutic adherence.

You could but your not leaving much room for you to breath. A window that tight is ok if your well on top of your readings and you know that you wont go out of this range, the problems will start if you have a bad night and need a little more.

Gazby, you can always escape from behind the iron curtain and come over here where they don't think it's a crime to change one's own CPAP pressure. Of course, the way our "Nanny State" is headed here, it won't be long until we're behind a similar iron curtain of "Big Brother" healthcare laws as well.

The folks who claim we're killing people by offering this "secret" knowledge of how to change pressures need to read this topic thread. Still haven't read one obituary that attributed the cause of of death to "CPAP Self Titration"... or even listed it as a contributing factor to anyone's death. I think I'll be waiting quite a long while before I see that.

Good to see you here, Gazby! I tip my teacup to you from across the Big Wavy Pond.

I have decrease to 6.8(max) and the 95% decrease to 5.5.
