Last nights numbers. What do they mean?

I am trying to figure things out like trying to get numbers lower and such. I think (Can not confirm or deny) that I may have had my mouth open a tad here and there..

Total Sleep Time 7.8
Leak 7.2L/min
AHI 6.7
Total AI 6.2
Central AI 3.3

EDIT: I should note that my pressure is set to 10

I know what the total sleep time means But the others I am still trying to learn so I have a better understanding, I will at some point start using the resmed software to get more detaild reports but for now in my NOOB days just use the on screen data.

The info on the lcd screen of the S9 really is quite good. To get your daily data, check before noon, because the next day starts at noon.

Total sleep time is actually total usage time. The machine has no way of knowing if you are awake or asleep.

Leak is leak rate measured in liters per minute. While 0 is the goal, ResMed's recommendation is to keep it below 12 liters per minute, as it can compensate for leaks by raising the pressure. But if it's over 24 liters per minute, then it starts to affect both therapy and the accuracy of the results. Leaks can be mask or mouth leaks, and the machine doesn't differentiate. To make sure your leak rate is measured correctly, make sure your Mask Setting matches the mask you are using.

AHI is apnea-hypopnea index, which the number of apneas and hypopneas, divided by hours of useage. AHI is made up of
1. Apneas--Central, Obstructive, and Unknown; and
2. Hypopneas.

The lcd screen doesn't show everything, so you need to do a little arithmetic, if you're not looking at your software:

AHI 6.7 minus AI 6.2 = HI .5

AI 6.2 minus CAI 3.3 = OAI .9

Here is the link to ResMed's Data Guide--page 4 has the definitions:

As a noobie, I would suggest focusing on 1. useage--keeping the mask on is a challenge for many. And 2. leaks--learning how to adjust your mask for leaks, setting up a hose management system, and head pillow that doesn't dislodge your mask if you side sleep. And if necessary, addressing mouth leaks, by using a chin strap, papcap, or full face mask.

We need time for our bodies to adjust to cpap at first, so unless you are very uncomfortable at your current pressure, I wouldn't make any changes for a week or two. I found that my numbers dropped, without any changes in pressure.

Hey Katie Thanks for the info..

The pressure setting of 10 is fine in fact is seems low to me at first when I put the mask on I am like oh boy here we go here comes the AIR I am using the ramp on the S9 starting at 5 and ending at 10 in 20 mins. Whats odd is when I first put it on it takes me a moment to get used too as I am sure it did for most, but when I wake up and its been going full pressure all night it do not seem to have any issues and almost feel like I want more air when I lay there for a few mins with it on before getting up lol.

One thing I have discoverd and ove is I can now go back under my covers. I used to love to just go all under my covers head and all but a few years back I just couldn't seem too do it any more probably due to the apnea and such but now with my mask I found out two nights ago I dived under the covers with fresh air ALL NIGHT LONG.

I think I will be dropping the ramp option before to long as even starting at 5 I feel like im not getting enough air when I first lay down and that can make it harder for me to pass out lol

Lots of us feel like that. Cutting the amount of ramp time and starting higher than 5 are alternatives to dropping ramp altogether. Ramp time on an S8 can be as low as five minutes, but I don't know about the new S9s. For those of us with simple cases of obstructive apnea, I don't think the doctors care at all what we do with our ramping. It is purely for comfort, so whatever puts us to sleep is fine.

I don't have quite as much love for covering my face with my blankets as the original poster, but it really does come in handy sometimes in a hotel room where a fan or air conditioning vent is blowing uncomfortably at your face. I wonder if I could sleep under water in the bathtub if I arranged things correctly?

Thats part of the reason I like my head under the covers is my wife has to have a fan running both for a lil air flow and white noise I guess. However the fan is on my side and at times can wake me up along with the other things that go bump in the night LOL..

Just be careful doing that, Biggie. The vents that let the CO2 out of your mask should NOT be blocked or you'll be rebreathing CO2...not good.
