SEVERE NIGHTIME HYPOXIA TREATED BY CPAP?

[Kate]

Because of the results of my first sleep study it said that I have severe nightime hypoxia and they were treating it with CPAP. By the time that I had my second sleep study, three months later, they told me it was cleared up.

Anyone else with this experience?

Nope, have not heard of this but hopefully some of the more experienced people will be by and help.

Just a WAG here Kate, since I don't really know what your docs were looking at, but Docs often focus on the "result" of a problem rather than what caused it in the first place.

So if they determined you had "severe nighttime hypoxia," rather than saying "Oh, you have Sleep Apnea, and that's known to cause "severe nighttime hypoxia," they just put you on a CPAP machine. And that "corrected" the problem. In other words, control the apnea, control the effects.

I have mild apnea but severe nightime hypoxia.

retired_guy pretty much covered it.
The word apnoea translates (approximately) as lack of air. Therefore to suffer from nocturnal hypoxia (oxygen desaturation) you must either stop breathing or have a restricted airway as you sleep. To remedy this, CPAP was prescribed for you as it was for all of us. In my case, an oxygen concentrator was also prescribed. That was over 14 years ago. and I sleep with it turned on every night The supplemental O2 won't prevent nocturnal desaturation in the event of central or full obstructive apnoea, but helps keep up O2 levels in cases of hypopnoea. It also speeds up recovery from hypoxic events. Thus you are among the lucky ones who have achieved maximum benefit from CPAP therapy.

Hi Kate,

Mild sleep apnea refers only to the average number of how many (5 to 15) Apnea plus Hypopnea events are occurring per hour, not to how deep the O2 desaturations go.

Severe nighttime hypoxia refers to how deep (SpO2 under 75%) the desaturations go during events.

Apparently, with PAP treatment your hypoxia events are no longer as deep.

I am prescribed supplemental O2 from a concentrator induced into my CPAP flow.
CPAP can improve desaturation in several ways -- first by reducing apneas.
But, second: Some people with OSA will also have areas of collapsed air sacs in the lungs called Atelectasis.
Some of these collapsed air sacs can be recovered by positive airway pressure.
