Bronchophony - Abnormal | Auscultation #139 | Lesson with Audio

patient thorax when auscultating by stethoscope

patient position during auscultation
The patient was sitting during auscultation.

Description

Ask the patient to say '99' several times while auscultating the chest walls. Over consolidated areas '99' is understandable. This is because acoustic filtering is reduced in consolidated lung tissue, which allows better sound transmission. Compare this breath sound to the recording in the Bronchophony - Healthy lesson.
