If a patient has chest congestion after exercise, it is usually necessary to monitor the patient’s heart rate immediately. If the chest congestion is caused by a fast heart rate, it is usually not appropriate to stop exercising immediately, for example, if the chest congestion is caused by stopping exercising immediately after fast running, it is appropriate to take a brisk walk and slowly reduce the heart rate to normal, which can improve the situation of chest congestion. If after strenuous exercise, severe chest congestion occurs, oxygen therapy should be given when available, i.e. oxygen therapy, using oxygen bags, oxygen cylinders for oxygen intake. If the patient is not relieved by the above methods, and the symptoms of chest congestion are severe, you must immediately go to the hospital to rule out the cause of pneumothorax or arrhythmia caused by excessive exercise.
