When you inhale and exhale, the air in your lungs and airways may create turbulence called respiratory sounds — also known as “lung sounds” or “breath sounds.” You may know these sounds as “coughing” and “wheezing” but there’s actually a lot more to these sounds than you might initially realize. Breathing sounds are not only used to help diagnose lung conditions like COPD, asthma, and pneumonia but they can be used to assist medical professionals in directing and prescribing medication for these lung diseases.
