When used without qualification, the term "blood pressure" refers to the pressure in a brachial artery, where it is most commonly measured.
An auscultatory gap, also known as the silent gap, [1] is a period of diminished or absent Korotkoff sounds during the manual measurement of blood pressure. It is associated with peripheral blood flow caused by changes in the pulse wave. [2] The improper interpretation of this gap may lead to blood pressure monitoring errors, [1][2] such as an ...
