Just diagnosed / Luna G3

Thank you all for this board and the invaluable information! I was just diagnosed this summer with severe OSA (AHI 53)

Diagnosis was with a Type III study. I asked for an in-lab study from my doc and was denied - the response was "it will not change any course of action"
I was given a Luna G3 (before I dug into research and understanding of sleep apnea).
Set to Auto with a 4-15 pressure range

Now that I better understand the need for data and really learning what is happening breath by breath, I am strongly considering a move to a different machine with OSCAR compatability.
I am also questioning the auto cpap (wouldn't this be more reactive than pro-active?)
Wondering if anyone wants to give some insight with the limited data I have been provided for two nights sleep:

Thank you!

Reactive is good in this place, and Apap is proactive if used correctly. Most people find that 4 is hard to breathe at tho' so generally move it 6-7 (and leave the max setting at 20, which is more usual than 15 here). Luna is not usual here tho', only overseas, so most also are unfamiliar with it except for the experts (like Pugsy).

Cute cat!

Welcome, SJVconsult! I basically agree with Julie but thought I'd go into a little more detail. I also have a question for you.

Your PAP machine is already "proactive," because the pressure is heading off many, many potential obstructive apneas, judging from your sleep study results. Like all PAP machines set to auto mode, it's also "reactive," in the sense that it will increase pressure in response to signs of airway collapse (snores, flow limitations, and of course obstructive apneas). This is aimed at heading off future events.

So why does the pressure then go back down? That's to provide greater comfort for the PAP user. The algorithms governing the machine do a balancing act between having pressures high enough to treat apnea and low enough to be tolerable.

You can't possibly hurt yourself by raising your minimum. This might head off a few more obstructive events yet still be comfortable for you. Like Julie, I'd suggest trying 6 or 7. You could raise your maximum, though this won't make any difference, given that your maximum actual pressure doesn't exceed 9.

The question: overall, how are you feeling? Sleeping fairly soundly? Feeling rested during the day? Feeling better than pre-PAP?

This is correct. With the home study, you were diagnosed with obstructive sleep apnea and prescribed CPAP. With a lab study, you would have been diagnosed with obstructive sleep apnea and prescribed CPAP.

A minimum pressure of 4, makes it more reactive and less proactive. Listen to Miss Emerita.

I know next to nothing about the brand itself. I know nothing about the specific algorithm itself.

In general we all know about how auto adjusting algorithms should work but that's about it.
The minimum pressure setting (when using auto adjusting mode) is the most important no matter what brand.

It does make the top 4 at the sleepfoundation.org.

It seems to be priced closely to the ResMed AutoSet.

That's about all I know.

That's a great philosophical question.

Auto CPAP uses a pressure range. The lower, minimum pressure is always there. I would call that proactive, because it's always working to keep your airway open. When the machine senses that you've had an obstructive event it will increase the pressure to try to prevent more of them, so that would be reactive.

So it's both.

It's a bit more than that.

How does the machine know to adjust pressure in AutoSet mode?
After you fall asleep and your pressure needs begin to vary, your AutoSet device responds to three separate parameters, based on the degree of airway blockage caused by your sleep apnea: inspiratory flow limitation, snore, and apnea. AutoSet devices automatically increase pressure as airway blockage starts to occur in order to minimise the chances of it developing into apneas.

At least that is ResMed. I don't know about Luna.

You're right, but TMI.

TMI.

Three Mile Island?

- or -

Information more personal than anyone wants, or needs, to know. A common problem on the Internet.

Person 1: I take this drug to help me sleep.

Person 2: Same here. It makes me drowsy.

Person 3: A friend of our family's son died from that drug. He had sleep apnea and he took a pill. He stopped breathing in the night and died. Worst part was, he was left in his house alone for 2 days and his dogs chewed his lips off.

Person 1: Holy %#&@

Person 2: Uh, TMI there...

Sincere thank you all!
I am feeling better for sure (still having some brain fog and tiredness but not nearly as much)
I will change the lower setting up a bit and see what happens.

Hi I was also just diagnosed and put on the Luna G3. I've only seen the data on their bad app. I'm not even sure how you were able to get the data you did. Any insight into that would really be helpful to me. Thanks everyone.

It's not bad though not at the same level as Oscar
