The blowing sound heard on auscultation is referred to as a?

A blowing sound heard during auscultation is termed a murmur. This sounds occur when blood flows through the heart or blood vessels, often due to turbulence created by conditions such as valvular defects or increased blood flow. Murmurs can be classified as either systolic or diastolic based on when they occur during the heart cycle.

In a clinical setting, identifying murmurs is important as they can provide insight into underlying cardiovascular conditions that might require further investigation or management. The other terms, while associated with sounds, represent different phenomena: a click often refers to a sharp sound, a whistle may indicate a high-pitched sound such as that from a narrowed airway, and a friction rub is related to the sound generated by the rubbing of inflamed pleural layers.
