I haven’t felt good today either. I finally took my oxygen levels and they are down to 88%. So it looks like I will be using the Oxygen machine again. I don’t know why all of a sudden they are down again as they had been stable at 91% for a long time. :-(
I hope your illness doesn’t last to long. Colds and coughs can be miserable.
Can you use the oxygen machine as often as you want?
