In short, if your AHI is nice and low, like yours is, and you are sleeping happily, then don't get too hung up on leak measurements.
It really shouldn't be that noisy. Very likely you have a leak, or possibly a loose connection somewhere. It is also possible that your new auto machine is pushing your pressure up much higher than the pressure your old REMstar was set at (causing some leaks). Which mask are you using?
Autoset machines, which is what you have based upon the pressure range you report, often get confused by PLMs (periodic limb movements) and increase the pressure unnecessarily. Increasing your pressure range is not going to help with you PLMs at all. In fact, the best course of action is usually operating in fixed pressure mode to prevent the machine from adjusting itself inappropriately. Your data from the period immediately prior to ceasing your medication should give a guide as to what pressure should work, although a new study would give the most reliable result.
The fact that there are columns just means that whoever was laying out the document was ill informed. The international standard rules for scoring sleep only allow for hypopnoeas, not obstructive hypopnoeas or central hypopnoeas. The columns doen't change that. Neither does that article. Whilst the theory is interesting enough, they will all get scored as hypopnoeas until the rules change.
It is also possible that some labs may decide to ignore the rules and do their own thing. That happens sometimes. Unfortunately it means the data they collect is no longer comparable to other data which does adhere to the standard rules.
I think you may also have misunderstood what I wrote. I certainly didn't suggest that hypopnoeas and central apnoeas are the same thing. See my post above for an expanded explanation.
I think you may be misunderstanding what I wrote. Whilst your hypothesis as to the cause of your hypopnoea is interesting it doesn't change the fact that, in medical terms, there is no such thing as a "central hypopnoea" because hypopnoeas are not classified as either central or obstructive. It's all down to the rules for scoring sleep. Apnoeas events are classified as either obstructive, central or mixed. Hypopnoeas are not. They are just hypopnoeas and don't come in different varieties. While we may make an informed guess as to the cause of a hypopnoea, it will always simply be classified as a hypopnoea because that is all the rules for scoring allow for. One day they may be modified to expand on this point, but until then we are stuck with only the one type of hypopnoea.
You may stop grinding your teeth once on therapy, but there's no way to be sure.
Sierra is correct, I was talking about the CO2 levels in your blood, not in the air. They are not usually measured in a standard sleep study because to do so requires some specialised and very expensive equipment. Some labs don't have this equipment and so having your CO2 levels checked can be tricky.
If I am understanding you properly, you are worried that the hole for you to breathe through your nose looks rather small. Don't worry, this is normal. If it fits well and is otherwise relatively comfortable, it's not a problem.
They could still work fine for you. It's hard to say without trying them.
