oxygen concentrators normally require a doctor’s prescription. I ended up being able to get one with a prescription. I figure I buy one and in case any of 8 of us get infected and they don’t have enough hospital grade ventilators this might help. Plus I know a few older people on my street that have asthma and might have problems and probably aren’t going to be proactive to prepare. The trick will be finding someone trained to shove a breath tube down there. I’m asking all my friends who are nurses which one had been trained to do it and can do it. You never know when it might be handy. ,
Can’t be too cautious to be overprepared for the long haul. Sort of like making slow drip investment over the years so when something drastic happens, you’re already a few steps ahead.
