Arterial pressure refers to the pressure exerted by the blood on the walls of the arteries as it flows through the circulatory system. This is a key indicator of cardiovascular health and is influenced by factors such as heart rate, cardiac output, and the elasticity of the arteries. Monitoring arterial pressure is important for assessing risk of cardiovascular diseases, such as hypertension, and is often measured using a device called a sphygmomanometer. Researchers in this area study the mechanisms behind arterial pressure regulation, as well as the impact of various interventions and treatments on maintaining healthy levels of arterial pressure.
