He had significant rales on exam with a CT scan demonstrating patchy bilateral ground glass opacities consistent with viral pneumonia (Fig. 1, left panel). Follow-up imaging 6 weeks after the initial diagnosis showed significant improvement but not complete resolution of the parenchymal changes (Fig. 1, right).
COVID-19 pneumonia post-discharge physiological data as measured by the RPM device. Decreasing respiratory and pulse rates are shown in the days immediately after device setup. Each data point on the respiratory and pulse rate deviation rows refers to the deviation of that day's median rate with the patient's all-time median baseline value. RPM setup is followed by a period of physiological stability then and a 2-day temporary increase in respiratory rate alone following COVID-19 vaccination.

In fact, steady declines in his respiratory rate and pulse rate deviations were noted post-discharge (Fig. 2). Except for a notable 2-day increase in respiratory rate corresponding to symptoms after COVID vaccination, the patient showed continued stability in respiratory rate and heart rate two months after hospital discharge (Fig. 2).
