The heart and lungs are the key organs in the body’s physical and pulmonary circulation. Cardiopulmonary function is the ability of the human heart to pump blood and the lungs to inhale oxygen. At present, some measures should be taken to improve the condition of cardiopulmonary function. Depending on their condition, they can be categorized into lesion type and subhealthy type. 1. Lesion type: There is some cardiopulmonary disease in itself. Generally, medication is needed to improve the cardiopulmonary function. Digoxin, etc. can be chosen under doctor’s guidance. 2. Sub-healthy type: It can be enhanced by some aerobic exercises. For example, swimming, jogging, climbing stairs, cycling, etc., both a certain amount of exercise, and exercise is not particularly intense, can play a very good effect in improving cardiopulmonary function. For people who do not exercise for a long time need to gradually increase the amount of exercise, so as not to cause life-threatening injuries due to heart attack in the process of exercise. People who need to improve cardiorespiratory function should go to the hospital in time to check the doctor, and under the guidance of the doctor to take a reasonable way to improve.
