Respiratory distress is a typical clinical manifestation of novel coronavirus pneumonia. Patients with novel coronavirus infection are divided into four types: mild, normal, severe, and critical. Patients with mild cases usually have a mild cough or fever, and rarely experience respiratory distress. In the case of the common type, the patient’s condition is mild and is characterized by a cough, fever, or some degree of dyspnea. If treatment is not timely or if the disease progresses seriously, the symptoms of dyspnea may worsen progressively. Further exacerbation may lead to respiratory distress syndrome, in which the dyspnea is very strong and respiratory failure may occur, and the patient may have other organ damage. At this stage, the patient often needs to be admitted to the resuscitation room or ICU for further resuscitation treatment. In this group of patients, the symptoms of dyspnea may vary according to their condition. Content source: Dr. You Lai
