Nonpharmacologic Airway Clearance Therapies
ACCP Evidence-Based Clinical Practice Guidelines
F. Dennis McCool, MD, FCCP; and Mark J. Rosen, MD, FCCP

Background: Airway clearance may be impaired in disorders associated with abnormal cough mechanics, altered mucus rheology, altered mucociliary clearance, or structural airway defects. A variety of interventions are used to enhance airway clearance with the goal of improving lung mechanics and gas exchange, and preventing atelectasis and infection. Method: A formal systematic review of nonpharmacologic protussive therapies was performed and constitutes the basis for this section of the guideline. In addition, the articles reviewed were found using the same methodology but were not limited to those that focused only on cough as a symptom. The MEDLINE database was searched for this review and consisted of studies published in the English language between 1960 and April 2004. The search terms used were “chest physiotherapy,” “forced expiratory technique,” “positive expiratory pressure,” “high frequency chest compression,”
