Bronchophony - Healthy

Have the patient repeat '99' while you auscultate their chest walls. With healthy lungs, this whispered phrase will not be audible due to impeded sound transmission. Be sure to compare your findings with an auditory example in our Bronchophony - Abnormal lesson!

Patient Sounds

Half Speed Patient Sounds

Technique

Auscultation Tips

Features:Ask patient to say "99" several times. Auscultate chest walls. Over healthy lung areas "99" is not understandable. Compare this sound to the Bronchophony - Abnormal recording.
