bronchial breath sound

bronchial breath sound

Etymology: Gk, bronchos, windpipe
a normal sound heard with a stethoscope over the main airways of the lungs, especially the trachea. Expiration and inspiration produce noise of equal loudness and duration, sounding like blowing through a hollow tube. The expiratory sound is heard during the greater part of expiration, whereas the inspiratory sound stops abruptly at the height of inspiration, with a pause before the sound of expiration is heard. Also called tracheal breath sound.
