will cental obstuction be diagnosed at the sleep clinic?

[tansey]

I asked this in another post but was not answered as the conversation moved into equipment talk
Also what will happen with the study when I lie awake from 2 until 4 or 5 AM which I usually do?

Hi, Tansey, you player of strange but beautiful instruments!!

Did you check the second page of your original thread? There are some responses to this particular question. There's one thing I forgot to say in my response. When naming what I know as types of apneas, this should have been at the end of the list... "or combinations of them." The person who posted after me alludes to that. Some of us aren't really sure what you mean by "central obstruction." Anyway, take a look at that, and hopefully others also will chime in here. Good luck with your study!!

thanks Marsha, i didn't notice the second page, daah!, what I mean by central obstruction is a neurological situation where me brain doesn't signal me to breath, at least that's what I understand it to be.
So you like the Uilleanns too They are a special magic.
off to my original post for page 2!

They are just considered Centeral Apneas. There are Central Apnea, Mixed apnea where you can have a central and obstruction at the same time, and just obstruction. I have all three, some mixed and some sperate.

I haven't seen the other thread - my apologies of this is a repetition.

a-pnea mean not-breathing. The breathing stop can originate in a physically obstructed airway, and would then be an obstructive apnea. Or the breathing stop can happen when your airway is wide open - and originate in your central nervous system's neglecting to give you body a command to breathe. This kind of breathing stop is called central apnea.

All breathing disturbances - regardless of origin can be seen at a sleep clinic.

and will they be able to tell you which kind just occurred?

[wlo2008]

The way they listed my apneas were the centrals were sperate, the obstuction were sperate and the mixed were sperate. And I had a number for each one. Telling me how many Centrals Apneas I had in an hour, How many Obstructive Apneas I had in an hour, and how many mixed Apneas I had in an hour. It will also list your Hypopneas verses you Apneas. It then will give you a combined Apnea-Hypopnea index.

thanks WLO. that is what I want.

My study included centrals. I woke up many times and I just settled back in, adjusting a wire or this or that and went back to sleep. Once, if I remember correctly, I had to visit the restroom. Now that's a real pain with the wire harness and all. Anyway, I slept the minimum amount of hours and they got good data so I left first thing in the morning.

[wlo2008]

I believe all they need is about 6 hours of sleep time to get. They asked me when I went to bed. And I asked to come in a bit earlier then I usually do, just because it would give me some extra time to fall a sleep.

Send you home for another PSG. If they get enough data for a diagnosis, you go away with only the diagnosis. If you are able to fall back asleep with a mask they will attempt to titrate to see if it improves your sleep, if not you have to go back for another PSG.

I had my titration the first night, so if you fall in the guide lines set by your doctor and the type of insurance company you have you might be able to get by with getting a titration that night, after the first two hours of sleep. If that is so you might be able to fall a sleep a little bit better after the mask is on. I know I did, but then I can fall a sleep anywhere and everywhere. LOL

But if you can tolerate the mask and pressure the first night like I did, not everyone does the first night, you will sleep a bit better during that time and may find your self a sleep at those times that you are usually up.

Going in with a positive additude is half the battle. Just know that you can do this, and know this treatment will make you feel so much better over time.

Good luck and keep us posted on how you do.

This is called a"split night study". It is what they did at my sleep lab. The tech asked me if I wanted the straight diagnostic or the split night and explained what it was (nice tech ). You can ask for it if you are not offered it, and if it works out, then you don't have to go back for another study, called a titration, where they try you with a machine and see what pressures will help you. If it doesn't work out, oh well, you just have what you would have had anyway

There is information attached to the "Our Wisdom" light bulb that tells what to expect during your sleep study, if you haven't looked there already.

Excuse me too if I am repeating already posted info. This is a very simplified def ...

The Central Apneas are usually identified in a sleep clinic when the see no effort to breath
- this is typically triggered by two main causes ...
1) The sleeper's brain fails to signal the respiratory system to work
2) The sleeper is on cpap & shows resistance to the CPAP pressure by stopping breathing (again no effort detected)

Obstructive Apneas usually are seen when there is an attempt to breathe but the airway has become blocked.

3) There is another type of Apnea (ref SAG) where it starts out as a Central Apnea but when the brain finally triggers the effort to breathe,
the sleepers airway has become blocked and it turns into an obstructive apnea.

In the sleep clinic they have several probes that look at
a) The chest & abdominal effort
b) Any airflow exiting or entering the nose & mouth

They are pretty good at picking the difference with ! & 2

I just learned about SAG. Interesting! Thanks : )
