27-year-old males have trouble breathing. Why?

The 27-year-old man had difficulty breathing, no obvious abnormalities were found in lung CT, blood gas analysis suggested hypoxemia, and oxygen partial pressure of 63 mmHg did not meet the diagnostic criteria for respiratory failure. A complete blood routine suggests an increased blood eosinophil count. Both lungs are full of wheezing sounds, and the symptoms improve after treatment. Examination of lung function suggests mild obstructive ventilation dysfunction.

Obstructiveness is hypoalveal alveolar ventilation due to increased airway resistance due to narrowing or obstruction of the airway.

Obstructive ventilation dysfunction is particularly characterized by a decrease in flow rate (eg, 1 second rate i.e., FEV1/FVC%) such as chronic obstructive pulmonary disease, emphysema, laryngeal edema, chronic bronchitis, bronchial asthma.

The man had a history of smoking, 70 years, had allergic rhinitis, and a comprehensive analysis diagnosed asthma. Dyspnea is caused by an acute attack of asthma. #健康过大年 #
