Abstract
Postoperative pulmonary dysfunction prolonging intensive care treatment after cardiac surgery most commonly occurs in patients with a background of pre-existing pulmonary dysfunction. However, many patients have occult dysfunction and present primarily after surgery. We describe and discuss the results of a respiratory optimization program utilizing a peak expiratory flow rate below 400 L/min as a screening test to identify patients in a nurse-directed preoperative clinic.
