Monitor the vital signs of severe high-risk groups, especially the finger oxygen saturation at rest and after exercise; Emphasis is placed on the role of hypoxia in clinical early warning of severe diseases. After slight activity, the oxygen saturation is less than 94%, so we should be alert to the deterioration of the disease.
