"O2 and monitoring SpO2 is IMHO the right path, but it's concerning they're getting no results out of the French protocol. Ain't liking that."

I too cringed at that observation. I could not tell, though, where in the course of care the HCQ had been applied. Waiting until conventional supportive care fails--when the pulmonary architecture is saturated with virus/fluids/inflammatory products--which sets you up for ARDS--is NOT the time to throw HCQ at the problem.

Wish I knew the sequencing.....
