120 events per hour

by Samuel S.
(United States, Wisconsin)

I started a sleep study and was put on a CPAP after about an hour or so. I was told that I had 120 apnea events per hour.

After continuing sleep with CPAP machine by morning improved on some scale of normal breathing of 1 to 26 apneas per hour - I scored a 24.

Question: if 40 events per night represent severe sleep apnea, what is 120 events per hour? thanks


Actually, if you have more than 30 apnea events per hour then your sleep apnea is graded as severe.

120 events per hour is...how should I say...a severe case of severe sleep apnea. Which is really bad.

I don't want to imagine how would you feel if you have such a severe case. For a seven hour sleep, this means 840 apnea events per night!

And when you think that one apnea event is defined as cessation of breathing for at least 10 seconds... Then in 7 hours of "sleep" you actually don't sleep at least 8400 seconds, which means at least two and a half hours.

The worse part is that you stop breathing in sleep exactly when you go into deep sleep, where your body is recovering from stress during the daytime.

In other words, you barely sleep during the night with 120 events per hour. As someone says, you "might better watch the sun rising".

A 24 AHI represents a moderate sleep apnea, which can still affect your memory, driving and work abilities, and your quality of life. See more about sleep apnea side effects here. However, it's a good step toward a better life.

I hope you'll get more support from your doctor to improve your sleep apnea index. Meanwhile, if you have any problems with your CPAP therapy, look for CPAP problems or Mask problems articles, or ask me in the forum section of this site.

I hope it helps. Don't be afraid to comment back.

129 per hour
by: Anonymous

Is there surgery for severe sleep apnea? I have claustrophobia and the CPAPA makes me feel like I'm suffocating but I have to do something about it as 129 per hour can be fatal.

Events per hour.
by: Anonymous

My MyAir report registers my registers my events at 0.7 or so, it has not gone to 1. What does this mean? Do I still have sleep apnea since it is under 1 ?

how about 185 times per hour?
by: Anonymous

I stop breathing 185 times per hour in my sleep and apparently these cpap machines can only be set to 10, but my prescription is 20. Whenever I have an event when using machine I wake up suffocating because I can't get the pressure I need. Any suggestions how to help me would be fantastic!!! I have many other health issues one being bursitis in both of my shoulders from only being able to sleep on my sides (very obese) and now the bursitis is so painful in both arms I find it very difficult to even attempt sleep and I can't sleep on my back, lower back is buggered and I just can't sleep on my stomach.

Is Sleep Science For Real?
by: Anonymous

My dad must have invented OSA. He was about 100 lbs overweight, had a very thick and short neck from playing college football, and was always tired.

He'd fall asleep in his chair each night watching tv and snore. After awhile he'd stop snoring, then breathing and then catch his breath and start over again.

He finally lost over 100lbs, kept it off and his snoring, OSA went away. Our mom was happy about that. So was our dog, who must have thought we were being attacked nightly by Martians who made weird noises.

When I found out years later I had it (sleep study, dr. ordered it) I couldn't believe it, I don't snore and I don't have big weight issues. I tried the CPAP for 5 months, hated it and finally used it as motivation to lose weight. Eventually, I stopped the CPAP and felt fine for years.

However, 10 years later I found out I had heart failure and other issues. So, due to the worst fatigue I had ever experiences, I went back on a new CPAP.

So far after a couple of weeks I've had mixed results. I feel a lot better and have some better energy but I feel tired most of the time and still can't stay asleep for more than 2 or 3 hours at a whack.

Hopefully I'll have enough energy now to get back in the gym and work off the weight, etc. But, I still have issues with OSA being for real, if the CPAP actually does much for it and what can be done to correct the problem in the future.

For me, CPAP is not fun, and the whole SA a bit of a mystery. For example, my AHI, etc, is at or around 4.0 now, the study said I had 20 events an hour, so do I now have 14 less episodes with CPAP? IF I take another study will I still have 20 episodes? And so on.

Guess many people have good results with CPAP, but seems like most people around my age (60ish) who have the machine stopped using it or don't use it much.

Now, the insurance companies are trying to max profits by forcing people to use CPAP at least 4 hours a night. Is that is make more money or to enforce the idea that you have to use the CPAP for it to work?.

There's hope...

I was at 89 apenas per hour and I couldn't get used to a COAL at all... I actually took the machine back 2 times thinking I was doomed however on the 3rd attempt I started getting used to it....


However now I recently dropped down to 7 apenas per hour after adjusting to higher pressure... I was skeptical about treatment however it's working now and I'm feeling better.... DON'T GIVE UP!!! I use The ResMed 10 and love my Cpap now.... Good luck because sleep apnea is PURE EVIL..
