Hmm, interesting. Have you tried it? If so, did it "work"?
I bought some of these when a close older relative had COVID, and there was no oxygen equipment for them because everyone else had it at the same time. They used them when they needed to get up and move around and they helped keep their blood O2 from dropping as much. By the way it seemed hard to tell how full or empty the can is by weight, you have to see if it still sprays which means it is not empty. I carry them in our small aircraft too but have never needed to use them.
