Patients with mild symptoms (i.e., fever, cough, expectoration, and other upper respiratory tract symptoms), and without abnormalities, or with mild changes on chest radiography, were classified as non-severe types. A mild change in chest radiography is defined by multiple small patchy shadows and interstitial changes, mainly in the outer zone of the lung and under the pleura. Severe pneumonia was defined by the presence of any of the following conditions: 1) significantly increased respiration rate (RR): RR ? 30 times/minute; 2) hypoxia: oxygen saturation (resting state) ? 93%; 3) blood gas analysis: partial pressure of oxygen/fraction of inspired oxygen (PaO2) /FiO2)?300 mmHg (millimeters of Mercury); or 4) the occurrence of respiratory or other organ failure that requires intensive care unit (ICU) monitoring and treatment, or shock .
