Patients with pulmonary nodules need to develop a light and frequent exercise program, such as lip-contraction breathing, balloon breathing exercises, and abdominal breathing. 1. Small-lipped lip-contraction breathing increases respiratory capacity and relaxes the muscles of the whole body before exercise, which reduces hypoxia. This method also exercises the internal muscles of the chest wall, improves muscle vitality, reduces oxygen consumption, decreases muscle strain, and improves lung function. 2. Balloon blowing breathing exercise can increase lung capacity and expel the gas accumulated in the chest, which is helpful for the recovery of lung function. It should be noted that do not strain, lungs do not adapt to rest for a moment before exercise, in order to avoid damage to lung function. 3. Abdominal breathing can expand the range of motion, improve lung ventilation, and improve cardiopulmonary function. It is recommended that patients adhere to a small number of exercise policy, exercise process discomfort in time to consult a doctor.
