Hyperinflation Respiratory Therapies in Cardiac Surgery Patients: A Randomized, Observer-Blinded, Prospective Clinical Trial
University of Texas Southwestern Medical Center
Summary
The purpose of this prospective randomized clinical trial is to evaluate three different types of hyperinflation respiratory therapies, Intermittent Positive Pressure Breathing (IPPB), Intermittent positive end expiratory pressure (EzPAP), Metaneb. Investigators will examine which hyperinflation therapy provides better lung expansion and may improve lung recovery after surgery.
Description
Postoperative pain due to surgical incision may limit lung expansion. After cardiac surgery, all patients receive respiratory therapies, because it is critical to expand lung after surgery to prevent respiratory complications such as lung collapse (atelectasis) due to shallow breathing or accumulation of airway secretions. Although incentive spirometer is the most common method used for lung recovery after cardiac surgery, some studies were not able to find any benefits from the use of incentive spirometer. Inspiratory positive-pressure breathing (IPPB), Intermittent positive end expiratory p…
