Why is it difficult to localize auscultation findings of the thorax of a newborn?

Question

Quizplus · Accepted Answer

Auscultation of the newborn can sometimes be difficult. The newborn's chest wall is small and sounds easily transmit from one lung region to another. Abdominal sounds may even transmit to the lungs, although bowel sounds heard from the chest in place of absent breath sounds may indicate a diaphragmatic hernia. Localizing auscultation findings in a preterm infant is frequently difficult or impossible with single-head stethoscopes. Auscultation with a double-head stethoscope has proved useful in some situations.
