Pleural friction rub

Overview
Overview
Pleural friction rubs are creaking leathery lung sounds, that is both inspiratory and expiratory. Pleural and visceral linings become inflamed due to rubbing during the respiratory process. Sound is consistent through inhalation and exhalation. Pleural rubbing is characteristic of pleurisy and is associated with pleural effusion and chest pain when breathing.
