Thanks Wondering1, so glad about your cousins happy ending!

Thanks dataq1 thats a lot of food for thought. We need an inlab sleep study for sure. Whether we will be able to get one or not I just don't know. The starting point is the sleep report and then to try to get someone to talk to me. Clearly he is being undertreated. If there was more minimum pressure...

Got it, thnx.

Thanks for this Ozij. So if i have understood you correctly, all (or most) of these central apneas could basically be a bit of an artefact? That is, response to arousals? Just a bit of a delay before the centrals start appearing. So by and large he is being undertreated at too low pressures and EPR ...

So I have had a look at the pattern of flow limitations, pressure change and apneas over a few days (as suggested). A flow limitation invariably leads to a rise in pressure. But that does not always coincide with an apnea. Sometimes it does. But there are many apneas appearing where there does not s...

Ok thnx I will have a look at that this evening.

So Ozij suggested trying to track the relationship between the flow limitations, central apnea and pressure swings. Does this reveal anything? I'm a bit lost at this point.

Yes that is indeed a very interesting discussion. I'm going to get the sleep report and take it from there. I have my suspicions but am not leaping to conclusions yet.

Thanks.

I will definitely get a copy of the sleep study as clearly it will hold many answers. It was an at home study so it might not have as much information as an in lab study.

Thanks everyone. Apparently there are no cardiac issues. He sees a cardiologist every six months to a year as he has POTS syndrome along with the chronic fatigue. In fact he has seen 3 sets of cardiologists over the last 10 years. They all say that his heart is fine. No treatment for the POTs beyond...

Thanks for the reply Miss Emerita. We live in the UK and can probably get it ok. He is not on any medication at present, no narcotics, no altitude. Here is a link to some centrals from a few days previously. Just under 10 mins I think. It doesn't look like arousals to me (based on what I have read h...

Many thanks for the replies. We don't have a copy of the initial sleep report but will try and get hold of it. He was told in the letter that 'there is a degree of obstructive sleep apnea'. However when I look at oscar charts it was basically central apneas from the first day. I will ask him about c...

I think this is a link to the Oscar chart.

Hi My son has been using a resmed airsense for just over 3 months now but no change in excessive daytime sleepiness or fatigue. He has had chronic fatigue for 10 years and is on disability benefits. When I look at his oscar charts I see that his median tidal volume over the three months is 360 and m...
