Every household should have a pulse oximeter, just as you have a thermometer for checking fever.

My physician parents have had one for years -- an old-school, giant box. After I came home from my #COVID19 hospitalization, I got a finger-clip one.
Here's a good FAQ on pulse oximeters. As Dr. @annamariechang told @taraparkerpope, don't stress over the make or brand; "it’s fairly straightforward technology."

(But get a REAL pulse oximeter; iPhone app = crap.)

Here's an op-ed from today's @nytimes by 4 critical-care/ER physicians (incl. Dr. Richard Levitan, whom I've mentioned before) urging required pulse oximetry in nursing homes. Early detection of #COVID19 can help greatly in treatment.
