I can understand that as my O2 drops, my HR will increase to bring the O2 back up. What I don't understand is why my HR goes up when my O2 is 96 or more. When I sleep, my HR will drop to the hi 70's. During the day, it stays in hi 90's or more with no activity. Is my heart working harder because it's going faster? Isn't this why 'normal' people do cardio workouts? At this point in my COPD progression, I worry more about heart damage than lung function.
My BP is great & my nurse says a HR of 130 or less is OK, but I('d still like to understand it.

Gettin old ain't for wussies!

I sometimes have that issue, and it means the heart is beating faster to meet the O2 needs. Add in caffeine and medication that can increase heart rate.

I have had a higher than normal heart rate for all of the 23 years since I was first diagnosed. I'm now 78 years old and when I gently exercise on the treadmill I keep my O2 in the mid-90s and--depending on the day--my heart rate varies from the high 90s to near 120. So far, no heart problems. I am convinced the benefits of exercise far out-weigh any other factors.
