How significant is AHI of 41?
So, I just received the results of my sleep study: AHI of 41. I know that >30 is severe and I now understand why prescription was given before my appointment with the sleep doctor.

With the CPAP therapy, my AHI has gone down to a bit over 10 and as has been only a week I expect that it will decrease with time.

That being said, how significant was this AHI of 41?

Thanks.

RE: How significant is AHI of 41?
depends on how long the events are. 41 is severe apnea, but i believe extremely severe apnea refers to that which is AHI 100 and up

Tongue Suck Technique for prevention of mouth breathing:
  • Place your tongue behind your front teeth on the roof of your mouth
  • let your tongue fill the space between the upper molars
  • gently suck to form a light vacuum
Practising during the day can help you to keep it at night

wayne99,
It's good that your AHI has come down, but like you said, it's only been a week.
Give it another week, and consider posting some data here from SleepyHead.

This is the scale used by most sleep clinics:
An AHI of 0-5 is considered normal.
An AHI of 5-15 is considered mild apnea.
An AHI of 15-30 is moderate.
An AHI reading of >30 is classified as severe sleep apnea.

Your goal is to get your AHI under 5.

To answer your question of significance, you have severe sleep apnea, but what's more important is the breakdown of your events. Are you experiencing mostly Obstructives or hypopneas. What about clear airways? This is the makeup of your total AHI number.

You are entitled to a copy of your sleep test.

This answer is so unhelpful, scary, and is quite misleading. You do not die of sleep apnea unless it triggers a heart attack or other significant event like a complete and irreversible cessation of breathing.

Many people test with high AHI and have not developed deadly co-morbidities like pulmonary hypertension (which has no cure and may require a lung transplant) or cardiac issues like atrial fibrillation that could throw a clot leading to a stroke, or ... etc.

Be thankful that the individual's condition was diagnosed and is now being treated. And, think before you scare the crap out of someone and raise their stress levels .. especially newbies who look to this forum for explanations, advice, and mutual comfort.

Thank you, srlevine, for that answer.

AHI means the person had X events average per hour.
Apnea events (both obstructive and central added together)
plus
Hypopnea events
divided by time

So an AHI of 41 means you had an event 41 times an hour which is roughly once every 1.5 minutes. What happens during any event is the blood oxygen drops and the body responds. Chemicals, toxins, twitching, snoring, you start to wake up just enough to open your throat and the event ends (if hypopnea or obstructive). Rinse, repeat. Sometimes you can have several per minute. Sometimes you can go quite some time without one. That's why it is an average. Over time, various organs and body systems start to suffer from this oxygen deprivation and lack of decent sleep.

The thing is you are getting treated now. You are taking charge of your health. Any damage that was done can quite possibly be reversed or at least easily treated now. High blood pressure decreases almost immediately. Our brain settles down. Our heart is happier. Our lungs are able to do its job. Every cell in our body is getting the right amount of oxygen finally. It can take time for it all to happen. Just like a person with diabetes has to figure insulin out, so do we have to figure out the pressure we need.

Give it time. Work with your doctor. Get a copy of the sleep study and a copy of your prescription. Keep them on hand in case you ever need them again (chances are you will).

RE: How significant is AHI of 41?
And I really wish they would redo the diagnosis criteria. So many people are unnecessarily freaked out when they hear their sleep study AHI. Like, mine was 68 I think. If the cut off for severe is 30, mine was TWICE that? OMG! I'm dying? Why are they taking so long to get what I need? Can I safely sleep until then? What the heck am I going to do?? Those two weeks I was miserable. And I shouldn't have been.

RE: How significant is AHI of 41?
Thanks for the responses. I was told today by the sleep clinic that they are unable to provide much info because I need to review with the Doctor, and that is scheduled two months from now. However, I insisted that I wanted to know the AHI. With their response, they also offered that if I am not compliant with the cpap therapy, I would likely loose my licence as they have duty to report.

She also said that oxygen is not really getting to the heart and the heart does not really have a chance to rest in the night.

Anyway, I have high blood pressure - been as high as 240 over 118 resulting in hospital, but typically around 160 over 105 or so. I have been eating healthier over past several months and manage now go get bp around 130 over 95. Tonight measured again and is 118 over 78. I have read that some people who have severe sleep apnea and high bp, the high blood pressure can go down with CPAP. Anyone here experience that?

I am grateful for this forum and the advice given. Thanks.

G'day Wayne

Congrats on getting your BP down so far - that's a very positive outcome.

In my own case my BP was staying stubbornly high despite medication, but after a while on CPAP and some lifestyle changes it has come down to a similar number to your own. The CPAP has also totally cured my ectopic ventricular contractions, which is why I was sent for a sleep test in the first place.

I agree with Paula that the diagnostic categories should be revised. There should also be a measure of the frequency (AHI) combined with the duration for a more meaningful measure of the potential damage being done.

RE: How significant is AHI of 41?
I think more than half the members here have untreated apnea as high or higher than your results. It's not atypical. Once you find the right mask machine, pressure and adapt to the therapy, you no longer have sleep apnea. You may use a CPAP, but you no longer will snore or stop breathing. It's like smoking where once you stop, you heal. It takes time, and if you had sleep apnea for a long time, then it may take longer to heal.

This is not too complicated. Get comfortable, sleep well, get better.
