The Effects of Incentive Spirometry on Pulmonary Volumes and Arterial Blood Gases After Coronary Artery Bypass Surgery

Abstract

Introduction: Following thoracic and abdominal surgery, all patients experience decrease in pulmonary volumes and atelectasis. Different methods are suggested for improvement of pulmonary volumes and blood gas parameters in these patients. In this study we examine the effects of spirmetry on pulmonary volumes and blood gases parameters (ABG) in coronary artery bypass patients.
