This was already reported in China since the very early days of the infection. People would come in with critically low spO2 that seemed to have no problems breathing but would then rapidly collapse. China switched to a system of centralized quarantine where people were put under medical supervision no matter how mild their case was and their spO2 was checked twice a day[1]. Anyone with spO2 < 93% was put on supplemental oxygen immediately rather than waiting for clinical signs. The American practice of allowing people to recover at home and make a self-determination of when they require hospitalization is likely causing many more excess deaths.
