Whispered Pectoriloquy - Abnormal

Lung Sounds Lesson

torso and chestpiece

Voice high frequencies are more readily transmitted to the chest wall in abnormal lungs as compared to normal lungs.

Ask the patient to whisper "1-2-3" several times while auscultating across the chest walls. The lung area is abnormal if the "1-2-3" sound is understood. This is the abnormal '1-2-3'.

Compare this sound to the recording found in the "Whispered Pectoriloquy - Normal" lesson.
