Figure 1 Differential pulmonary functional recovery from COVID-19 and
impaired diffusion function in recovered severe COVID-19 patients. A The
percentage of the pulmonary ventilation dysfunction among the three
groups,including MMEF%pred < 65%, FEF75%pred <
65% and FEF50%pred < 65%. B The percentage of diffusion
dysfunction among the three groups,including DLCO%pred < 80%
and DLCO/VA%pred < 80%. C The percentage of the lung volume
among the three groups,including TLC%pred <80% and RV%pred
<65%,and the value of RV/TLC (actual/pred).
