Patients with severe neo-coronavirus pneumonia infections may develop dyspnea and hypoxemia, and in severe cases may become acutely respiratory distress syndrome, septic shock, and difficult-to-correct metabolic acidosis and coagulation disorders, complications that may lead to death. The novel coronavirus may lead to viral pneumonia with impaired lung function or even severe impairment of lung function, resulting in dyspnea and hypoxemia. Especially the elderly or people who are weaker and have underlying diseases may also develop comorbid acute respiratory distress syndrome, leading to sepsis, shock and uncorrectable metabolic acidosis, coagulation disorders and other conditions, so the new coronavirus has a certain degree of lethality. It is recommended that you wear a mask when you go out, wash your hands regularly, and avoid going to places where there is a large flow of people.
