That's a horrible account and I hope she's on the mend sooner rather than later. Let's not overlook that she stated she's asthmatic.
The New England Journal of Med article is eye opening... the recommendations are put forward if medical supply scarcity reaches a point of no return/no escape. Physicians aren't yet using the recommendations based on how the article reads because we haven't yet reached that level of scarcity. I have hope that we (the world) will pull together and help one another with scarcity of medical supplies. I was heartened last night before bed when I read an article that stated that China is working 24/7 to produce ventilators for NY and I am greatly encouraged by companies willingly shifting production models to produce med supplies (Tesla, Ford, GM, Honeywell, etc). The NEJ recommendations are preparing medical staff for the possibility of an over-run, triage based healthcare system response. Hopefully we won't get to that point and Social Distancing will help keep us from getting there I believe.
