It's generally not encouraged because of the chance of a spark, but I've never had a heating pad cause a spark ever. I use then with and without 02.

I wonder why you couldn't use a heating pad with the oxygen?

No, I never use a heating pad with oxygen. I put a heating pad on my back during the day sometimes but I’m only on oxygen at night and I do not use a heating pad.

Thanks Jean. My arthritis is killing me!! Either way I’m dead!!

They say you shouldn’t because it could spark since it’s electric but don’t think that’s a high probability. I was asking if anyone was brave enough!!
