At present, patients who meet the discharge criteria should be rested, but not to be rested at home, but to continue isolated medical observation in the designated hospital for 14 days, and after 14 days of isolation, the new coronavirus nucleic acid test will be performed again, and the test result will be negative to be released from isolation. The lung images of patients with novel coronavirus pneumonia are interstitial changes, and some patients have pulmonary fibrosis manifestations that are not fully absorbed from imaging. Some patients have normal oxygen saturation at rest and a slight activity of oxygen saturation will decrease. The decrease of oxygen saturation will have a certain effect on the patient’s heart and lungs, especially the heart, and will not be conducive to recovery. Therefore, patients need to rest and should not perform too many activities or even rehabilitation exercises too early.
