When I had my test back in.... 2015? Same night as the Baltimore riots... turned out I was having upwards 60-70 events an hour. Essentially I was breathing about 1/3rd of the time, and suffocating the other 2/3ds.
The new machine I've been using since late last year has an app that tracks usage statistics, including events per hour.
In the last month, however, I've had only 8 days where I've had more than 1 registered apnea event per hour; most days it's in the .3 to .5 per hour range, and one day I had zero apnea events.
Last night was an odd one for me, though... just could not get comfortable with the mask. Turned into a very restless night all around, and I just looked and I averaged air leakage of 46 liters a minute. That's MUCH higher than anything I've had going on; most nights I'm in the 20 liters or less range for leakage.
