Sleep study shows my acap providing low pressure

[dwd1249]

I have to have a review every year with my sleep medicine physician to maintain my buss driver authority. He was bothered by the fact that my machine was only applying 7 - 8 cm of water. He expects some one my size to be 10 - 15 cm of water. So off to the sleep lab for an over night study.

I had my study with the outcome being my pressure should be 14cm of water. The Dr suspects that the low pressure provided by my acap could be due to the algorithm or my relatively narrow nasal airways.

I made some changes to my acap and got it providing 14cm of water and more at times during the night . Then 3 days ago I changed the machine to be a cpap at 14cm H2o and I feel better, not that I was bad before.

So I guess a Auto machine is not always the best. And that you have to keep aware of what is happening.

I can only speak for myself, an autoset works best for me, adjust pressure in response to snoring, flow limitation and apnea

I,m not familiar with Chinese made machines or know anything about them
