Patients can perform cardiorespiratory exercises through jogging, swimming, balloon blowing exercises, lip contraction exercises, etc. Exercises for healthy people and patients with chronic obstructive pulmonary disease (COPD) are also differentiated. 1. Healthy people: patients can improve their cardiopulmonary function with long-term and moderate aerobic exercises, which usually include jogging, swimming, cycling and so on. When exercising, patients should pay attention to the intensity of the exercise is not too high, the exercise time should be kept within 30 minutes, and to maintain long-term exercise and can be carried out three to five times a week. 2. Patients with chronic obstructive pulmonary disease (COPD): If patients cannot tolerate long-term exercise, they can reduce the exercise time appropriately to avoid discomfort. At the same time, you can also choose to blow up the balloon training, lip contraction training and other training to increase lung capacity, further improve exercise endurance, improve cardiopulmonary function. Patients can perform cardiorespiratory exercises under the guidance of a professional doctor, and if discomfort occurs, it is recommended to seek medical attention in a timely manner.
