How is percussion performed?
Percussion is an assessment technique which produces sounds by the examiner tapping on the patient’s chest wall. Just as lightly tapping on a container with your hands produces various sounds, so tapping on the chest wall produces sounds based on the amount of air in the lungs.
What techniques are used to detect lung sounds?
The vibrations of the chest–wall can be recorded using several different methods of transduction, such as condenser and piezoelectric transduction [56].
What is the normal lung sound?
Normal findings on auscultation include: Loud, high-pitched bronchial breath sounds over the trachea. Medium pitched bronchovesicular sounds over the mainstream bronchi, between the scapulae, and below the clavicles. Soft, breezy, low-pitched vesicular breath sounds over most of the peripheral lung fields.

When to use percussion in the anterior chest?
Percussion helps to determine whether the underlying tissues are filled with air, fluid, or solid material. Percussing the anterior chest is most easily done with the patient lying supine; the patient should sit when percussing the posterior chest.
How is percussion used to improve airway clearance?
Percussion is a manual technique used by respiratory physiotherapists to improve airway clearance by mobilising secretions in one or more lung segments to the central airways. Percussion over an affected area produces an energy wave, which is transmitted to the lungs and airways, loosening thick, sticky secretions from the chest wall.
When to use auscultation, percussion, or inspection?
While auscultation is most commonly practiced, both percussion and inspection are equally valuable techniques that can diagnose a number of lung abnormalities such as pleural effusions, emphysema, pneumonia and many others.
