Well said about senior citizens and brain foggynest. I see it all the time and encourage older folks to have a source of supplemental oxy. I’ve shown to others in the family how beneficial it can be. It’s easy for me to do since I keep a bunch of pure oxy and breathing equipment at the shop.
One thing that’s really, really, weird is that some folks resist getting extra oxy because it might cost something. Sometimes Medicare will help, with a doc’s order, and while they don’t complain about the price of a pill, somehow there is resistance to using something with NO SIDE EFFECTS.
On a side note, I sleep like my pet rock and fall asleep normally before I get all the covers just right. But on that occasional time when I don’t drop off right away I take a few deep inhales thru the nose along with quick, forceful nose exhales. Just for fun I do a ten count. I hardly ever make it to ten before I’m gone. My heart rate is normally 60ish but that little burst of extra oxy takes it down to 60, and the slower pulse just knocks me out. It’s good if you have an oximeter handy to learn what your pulse pattern might be.
I have one. Laying here watching tv. Oxy is 99 and HR is 66.
