Whenever my oxygen is increased from 3 to 4, I get headaches. They stop when I reduce it to 3.

When I was on oxygen I did get headaches but the God I am not on it anymore.

My supplier says that anything petroleum based is not a good idea, that means Vick's and Vaseline. I do have a water container attached to my device and that helps during dry months or in house dryness. I had some discomfort in my eyes at first; however, during exercise they gave me a.2 dose whereas at home I was getting .1 so I uped my dosage to .2 and the eye discomfort stopped.

I get headaches. I am no longer on oxygen

Hi! Retired respiratory therapist, with COPD, here. O2 is anhydrous, which means it has no humidity at all, and we all know what super dry air can do to our breathing. A cannula without humidity will cause headaches and runny noses.

you have to high a level of oxygen in your blood lower your intake , mine had to go from 2 to 1 then the headaches went away

Very true I keep my oxygen on all the time and when you wrote about your headaches a little light in my head turned on maybe that is why I wake up with headaches all the time never crossed the too.
Thanks worth looking into. A big hug for you

When I wake up with my cannula on the floor, my head is what actually wakes me up because it hurts so bad. I get terrible pain up the back of my head.. I always check my oxygen level and it's usually down to 92. As soon as I sit and it comes back up to 97, my head is fine, so yes, you'll probably get a headache. Oxygen is considered a drug, so once you're on it, it's kind of hard to get off.

I will sometimes wake up with a headache if somehow the cannula came out of my nostrils at night and if I take it off to do my meds in the morning and forget to put it back on, I will get a headache. I’ve been on oxygen 24/7 for quite a few years now. I had hoped when I moved back to Missouri from Colorado that I could go off of it, but no such luck!

I do get headaches while using oxygen. BUT I also have apnea and often stop or very shallow breathing, that is when I get the headaches. Awake or asleep.
