Arlene, one thing to keep in mind is that small numbers of apnea events (even central events) per night are normal. The measurement of the "seriousness" of sleep apnea is called AHI, or Apnea Hypopnea Index. It is the average number of apnea (obstructed + central) events plus hypopnea events per hour. [ A hypopnea event is just a partial reduction of breathing for more than 10 seconds, as opposed to an apnea event which is a significant or total reduction in breathing for more than 10 seconds. ]
An AHI value of 5 or less is considered "normal". An AHI value between 5 and 15 is considered "mild". An AHI value between 15 and 30 is considered "moderate". An AHI value above 30 is considered "severe".
Now, it turns out that patients often display "central" apnea events while being titrated (determining the proper treatment pressure) for obstructive apnea. These will often disappear as the patient grows accustomed to the CPAP therapy.
Having said all of that, almost none of us here are doctors. I'm certainly not. I've simply educated myself about my condition. With that in mind, if you would like me to have a look at your husband's sleep study result, I can give you my opinion.

His AHI was 26.8 per hour.
before CPAP, he had 1 obstructive apnea, none after
before CPAP, he had 9 central apnea, 7 after.
There are 33 hypopneas, spread before and after.
Im concerned, because the manufacturer told me that this machine is not used for CSA. I just want him to have the correct machine.
Can I post the study on this board as a picture?
