A one-page memo could defuse the panic about Trump’s COVID-19. Where is it?

Here’s what they need to know:…

2. Trump’s oxygen saturation over time

Sean Conley, the president’s physician, said Trumps’ oxygen saturation, or SpO2, was 96% Saturday morning. That’s a good number, but the physicians STAT spoke to said getting a figure at a single point in time was not enough. One needs to know what the lowest value seen was, and how the number changes if Trump is moving around.

“It may not be big shifts, but people can go back and forth,” said Nahid Bhadelia, medical director of the Special Pathogens Unit at the Boston University School of Medicine. A patient who is fine in the morning may have trouble breathing in the evening.

3. A chest X-ray or CT scan

A chest X-ray, and possibly a CT scan, would be among the most basic and informative information about the president’s health. Conley mentioned giving frequent ultrasounds, but did not mention these more normal tests. A description of them could shed a lot of light, and the images themselves would be worth 1,000 words. “It would be nice to see his pictures,” said Narasimhan.
