Coughing is a common symptom of the new type of pneumonia, but the frequency of coughing varies from person to person, with some coughing more and most coughing dry. If it causes an irritating cough coupled with dyspnea, the patient will feel very uncomfortable because it is difficult to cough up sputum, and there is a lot of exudate in the patient’s lungs, which makes the mucus very viscous. The patient’s own breathing difficulties, and mucus can not be discharged when the cough will be triggered, most of the patients in the later stages of severe disease, due to respiratory failure and respiratory distress caused by airflow restrictions, insufficient respiration, coughing is not necessarily very heavy, can not be used to cough to indicate the degree of infection, because sputum can not be discharged is the main problem, the more the more the lack of coughing, but the condition may worsen, because the patient is not able to cough.
