The most commonly used training methods include upper limb training, lower limb training and respiratory muscle training, which can make the patients’ 6-min walking distance significantly longer, and the respiratory muscle strength and endurance are significantly improved. Lower extremity training is the core of exercise training, including endurance training and strength training, endurance training in the form of fast walking, rowing, cycling, hiking, etc., and strength training, including power cycling, exercise plate, etc. The American Thoracic Society believes that upper extremity training is the core of exercise training, including endurance training and strength training. The American Thoracic Society believes that upper extremity training can increase the mobility of the upper extremities and relieve symptoms of dyspnea. It mainly includes hand crank. Hand-held weights start at 0.5 kg and increase to 2-3 kg, and are performed in all directions above the shoulder, with a rest period of 2-3 minutes for each 1-2 minutes of activity, and rotation of the shoulder joint, twice a day, monitored for mild shortness of breath and upper arm fatigue. Most of the training programs include a variety of training methods, combined with the current actual situation, the patient’s left Mr. lower limb strength and endurance training using fast walking and power bicycle training methods. Specific respiratory muscle exercise methods mainly enhance the respiratory muscle strength and endurance, mainly including abdominal muscle training, enhancement of inspiratory muscle training. Abdominal muscle is the largest expiratory muscle, enhancement of abdominal muscle training commonly used methods are horizontal abdominal breathing resistance training, blowing candles, blowing bottle training, taking into account the safety and the actual situation of our hospital, the use of horizontal abdominal respiratory resistance training, supine position, the 1kg sandbag placed between the umbilicus and the pubic bone of the lower abdomen, increase the weight of the weight of the two days every time, and gradually increased to 5-10KG, each time for 5-20 minutes, training 2 times a day. The patient was placed in a supine position with the head slightly elevated. First, let the patient master the diaphragmatic respiration that will be learned later, and then place a 1-2kg (3-5lb) sandbag on the patient’s upper abdomen. Let the patient take a deep breath while keeping the upper thorax calm, the weight of the sandbag must not hinder the diaphragmatic activity and the upper abdomen bulge is appropriate. Gradually lengthen the patient’s resisted breathing and increase the weight of the bag when the patient can maintain a diaphragmatic breathing pattern without using the assisting muscles for about 15 minutes. The minimum duration of an effective pulmonary rehabilitation program is 6 weeks. Exercise cycles: The longer the better, the longer you can continue to train at least 3 times per week for life, with a target intensity (60%-75% maximal oxygen uptake) of 10-45 minutes. Higher intensity training is the only way to get more effective exercise training benefits. Low-intensity exercise training has health benefits for long-term adherence and a wide range of people. Clinically, the Borg score of 4 to 6 is often used as the intensity of exercise training The method of exercise training is relatively common, but it is important to ensure that our rehabilitation therapists should actively cooperate with clinicians to patients Mr. Zuo’s own cardiac function, physical fitness of the whole body, psychological function and environmental function and other physical conditions as the basis; in the case of close observation to ensure the safety of the patient; to follow the individualized, holistic progressive Mr. Zuo’s heart condition was carefully observed to ensure his safety.
