Heart surgery is a kind of trauma and stress both to the patient’s organism and psychology, and this trauma will make the patient lose the ability to live for a period of time. In order to help the patient recover from the surgical trauma as soon as possible and make it close to a normal and good state, rehabilitation nursing is an essential means. Care attention I: The purpose of exercise therapy is to improve the range of motion of joints, enhance muscle tone, promote blood circulation, regulate the function of the main organs of the body, and improve emotion and daily living ability. Exercise can improve cerebral blood flow, increase heart rhythm and cardiac blood displacement, increase ventilation and promote the body’s recovery. Care attention II: joint exercise, joint exercise in principle to the proximal joints to the distal joints, but because of the upper limb movement on the chest incision, to help patients after cardiac surgery activities to start from the distal end of the lower limbs. The activity should be carried out slowly and should not be too large, and the patient can start the activity under the guidance of the nurse when the condition is stable, and the amount of activity should not feel fatigue. Joint activities should not be done when there is fluid input to the hands or lower limbs. Care note three: whistling exercise, after leaving the whistling machine, in order to prevent intrapulmonary infection and pulmonary atelectasis, to carry out appropriate whistling exercise and sputum training. Exercise methods are deep whistling, mouthwash bottle, blowing balloon, whistle trainer and soft pad to press the knife mouth to assist sputum, etc., can also wear elastic undershirt to protect the knife mouth. Care note four: the patient should continue to do the above movements after discharge. Exercise amplitude and amount of exercise can be gradually increased, such as walking training can be gradually transitioned from slow street to stairs, fast walking, pediatric heart surgery incision healing, but also practice arm expansion exercises to prevent “chicken chest”. Note 5: Patients who are not suitable for exercise, including severe cardiopulmonary insufficiency, postoperative fever, anemia, heart rate over 100 beats/min during quiet time, difficulty in inspiration, dizziness, chest pain or cyanosis during training, heart rate over 135-140 beats/min during exercise, heart rate over 120 beats/min over 45 years old, should be noted.
