I need help understanding these numbers.

Hi all! I have been having a rough time with feeling really unrested in the last month. My doctor told me to send in my card. I asked to have the report faxed to me and it might as well be written in Russian. My Doc has been pretty unresponsive to my concerns so I intend to change to another sleep lab for my next appointment. For now, I am really curious to know if there is anything wrong with the numbers in the report. (If past experience is any indication...it will take the Doc about 7 days to call me back.)

This is what I see on the report:
CPAP............... 9.0 (I understand this is my pressure)
Average Obstructive Apnea Index............. 1.2
Average Hypopnea Index.................1.1 Average AHI...............1.3
Average Vibratory Snore Index..........100.6
Average Max Leak........ 78.5
Average 90% Leak........38.5
Average Leak...............33.3
Average Large Leak......3.1 Secs.

The Summary is as follows:
Avg. Time in Apnea Per Day........1.3 Mins.
Avg. Time in Large Leak Per Day..........3.1 secs.
Avg. AHI.............................................2.3

Does this mean I have a mask leakage problem? Is anything out of the ordinary here? I am so anxious to figure out why I am not feeling good anymore. I feel like I did before I started with the CPAP. I am so frustrated. Any insight you can offer is appreciated.

The machine shown in your profile collects no useful data. The number you post shows the AHI to be fairly good for a base.

Avg. Time in Apnea Per Day........1.3 Mins. Is way our of line, the snoring is too. You may be mouthbreathing, letting the pressure come out of your mouth instade of holding your airway open. You will do it in deep sleep and not know it.

If you do have a data capable machine you need the software and data reader to follow your progress. Jim

Don't know why 1.3 minutes of apnea per day is way out of line, Goofproof. If your OSA index is 1.2 and you sleep eight hours, you've had about nine apnea events per night. If each of those was only ten seconds, you'd have a 1.5 minutes of apnea per day.

It looks like AHI should reall be 2.3 not 1.3 if the HI and OAI are correct ... but that's still darn good.

Average leak and 90% leak look fine, but you are clearly having some large leaks .... could be noted mouth breathing or could be mask dislodging when shifting during sleep.

Maybe I'm spoiled. My time spent in apnea is 15.771 Seconds, and my length of event is 8.19968 seconds, this is my avg for the year of 2007.

I started treatment with a AHI of 150, now I am down to AHI 0.72, it was better but I am getting sloppy with my med's.

What's more inportant is the length of apnea, If that 1 minute 30 sec, is one event, it might be the last. Jim

My DME has been trying to convince me to use a full face mask (it is just his personal preference) but I have been resistant because of clostrophobia issues. I might just have to break down and give it a try. I really love the Swift II, I forget I even have it on.

You may want to try a Hybrid instead of a regular full face mask. If your claustrophobia issues have to do with something between your eyes, this doesn't have anything like that.

My claustrophobia is more related to having both my mouth and nose covered. I feel a bit of panic but I would say it is relatively mild. It is not so bad that tehre is not at least a chance of adapting. I had not heard of the hybrid masks before. I will look them up to see what they look like.
