Question 28 - Is it necessary to treat hypopneas ?

From: J.

I had a sleep study done because of some lack of sleep. Here is what they found out: I had mostly no obstructive sleep apneas (average of 0.7 episode/hour), no central sleep apneas (average of 0.5 episode/hour), no mixed sleep apneas but I had an average of 19 episode of hyponeas per hour (hyponea is underbreathing is I understand well).

During the night, my average % of O2 saturation was 96 and I spent 12 minutes below 95% saturation (not all at once, only spikes), but no time below 90%.

So, my question is: Is that all bad? Do I really need CPAP? Of course the sleep clinic peoples want to sell me a machine…..

The hypopneas cause similar increased respiratory effort just like apneas. The cardiovascular risk remains.

Treatment is still recommended.

Good luck.
