Central apnea...moving to sea level

According to this study living at a lower altitude is better for many pepople with complex apnea.

"Conclusion:
This study demonstrates that central apnea becomes significantly more common at increasing altitude in both diagnostic and treatment portions of split-night polysomnography in patients with significant OSA. An apparent exponential increase in the percentage of OSA patients with a CAI > 5.0 occurs with increasing altitude. Altitude associated central apnea has a significant negative effect on the quality of OSA treatment obtained during PAP titration for patients living at the altitudes addressed in this study."

Before that I was at near sea-level in Michigan,

Just fyi, The lowest point in Michigan is 571 feet above sea level.

I know, I was there . You may be interested in the difference of the actual effect on breathing (ultimately, oxygenation): at 571 ft the standard barometric pressure (and thus, the partial pressure of oxygen) is 98% of that at sea level, or practically the same. At 5000 ft it is 84%, which is rather significant. The exact effects are rather complicated and are also highly dependent on the general heath of the individual. Here is a nice website that has some useful calculators: http://www.prognosis.org/physiology/
