Heart rate increases when oxygen drops because the heart has to work harder to get oxygen out to your organs and extremities.

Yes, it's common for heart rate to increase when oxygen levels drop. This is your body's natural response to try to get more oxygen to your tissues. The normal oxygen saturation range is typically 95% or higher, so levels of 89-93% without oxygen indicate you may need supplemental oxygen.

Yes, it's common for heart rate to increase when oxygen levels drop. This is your body's natural response to try to get more oxygen to your tissues. The normal oxygen saturation range is typically 95% or higher, so levels of 89-93% without oxygen indicate you may need supplemental oxygen.

Common symptoms of low oxygen (hypoxia) include:
• Shortness of breath
• Increased heart rate
• Reduced exercise capacity
• Fatigue
• Changes in skin color
• Mental fog Given your symptoms, it's important to have an open discussion with your doctor about why they want to discontinue oxygen therapy. If you're concerned about the recommendation, consider getting a second opinion from another pulmonary hypertension specialist. Oxygen therapy can be vital for preventing your condition from worsening, especially if you're experiencing symptoms when your levels drop.

AI seems to have misread your question, taking your heart rate range as your O2 range.

I'm not sure, but I believe the parameter for being on supplementary O2 is when your sat level averages 88 or lower.

And a heart rate range of 89 to 93 is not really bd. again, I'm not sure, but I think the goal for heart rate is between 60 and 90. But I know in my case, my heart rate is not considered to be high till it reaches over 100.

Maybe other people will stop by and add information here.
