What is pulsatile?

Pulsatile is a term used to describe something that exhibits a regular pulsation or rhythmic oscillation, often in the context of blood flow. In the human body, for example, the heart beats rhythmically, causing blood to flow through the arteries in a pulsatile manner. Pulsatile blood flow can be detected using various methods, such as palpation, auscultation, or imaging techniques like ultrasound. Abnormalities in pulsatile blood flow can indicate underlying health issues, such as high blood pressure or arterial stiffness. Pulsatile devices, like pulsatile pumps or pulsating air mattresses, are also used in medical settings to provide targeted therapy or support.
