Strong cardiopulmonary function is mainly manifested in the aspects of high lung capacity and strong exercise ability. 1. High lung capacity: usually hold the breath ability is stronger, the respiratory circulation function is good, obtain the transportation of more oxygen, lung capacity to a certain extent increased. If the lung capacity is relatively small, the usual performance of shortness of breath, short, may be a sign of cardiopulmonary function decline. 2. Strong exercise ability: patients with strong cardiopulmonary function will show stronger performance in exercise, can exercise for a long time and will not feel tired easily. Strong heart and lungs can get more oxygen through lung inhalation and exchanging air in time to maintain normal heart rate, and the intensity of exercise will be continuously improved. Normally, if there is any panic and shortness of breath, it is recommended to go to the hospital in time.
