Respiratory care of patients undergoing open heart surgery should begin in the preoperative period. Patients must stop smoking, and if obese they are encouraged to lose weight. Pulmonary infection is treated and secretions must be eliminated. ⋯ Oxygen therapy is given with either a nasal catheter or a mask, according to the patient's need. IPPB and physiotherapy are continued until the patient shows no signs of pulmonary infection and is capable of effectively eliminating secretions. This routine management and extended postoperative respiratory care definitely contribute to the successful outcome of open heart surgery.
