tactile fremitus

Introduction

Palpable vibrations transmitted through the bronchopulmonary tree to the chest wall when the patient speaks. Ask the patient to say 'ninety-nine' or 'one-one-one'.

Etiology

• obstructed bronchus
• chronic obstructive pulmonary disease (COPD)
• pleural effusion
• pulmonary fibrosis
• pleural thickening
• pneumothorax
• infiltrating tumor
• a thick chest wall
• tactile fremitus is increased when transmission of sound is increased as occurs in lobar pneumonia

* tactile fremitus is diminished when the voice is soft or when transmission of vibrations from the larynx to the surface of the surface of the upper back is impeded
