After lobectomy, pulmonary rehabilitation can promote pulmonary resuscitation, improve pulmonary ventilation and exercise endurance as follows: 1. Cough and sputum training: 24-48 hours after surgery to facilitate sputum drainage and prevent pulmonary infection; 2. Respiratory training: After the patient is awake, respiratory training or assisted respiration is performed by placing the hand on the abdomen during inhalation, cooperating with the patient to press down hard during exhalation, and letting go quickly at the end of inhalation to promote pulmonary resuscitation, or a respiratory trainer can be used to strengthen respiratory muscle strength training and promote sputum expulsion through vibration.
