Abstract

Respiratory medicine relies both on clinical information and on complementary, laboratory tests results. However, despite today’s technological wonders, a proper history and a sound physical examination have no substitute as the initial step in making a correct diagnosis and, by consequence, providing the appropriate treatment. Respiratory complaints are frequently the cause that brings a patient to the doctor, and the respiratory system is the most commonly affected organ system in clinical practice. Consequently, respiratory sounds, either heard at a distance or auscultated over the chest, are integral to the evaluation of patients and may provide valuable clues. This chapter focuses on lung sounds as they are reported by patients (or by their guardians in the case of young children) and as a sign noted on chest auscultation performed with the stethoscope. The characteristics and the pathogenesis of adventitious breath sounds (stridor, wheeze, crackles, squawk) are briefly addressed and their clinical usefulness is discussed; voice-transmitted sounds and noisy breathing (grunt, snuffle, rattle, snore) are also presented. The four clinical cases included at the end of this chapter highlight the value of the proper understanding of breath sounds.
