hemodinamikát

Hemodinamika refers to the study of blood flow through the circulatory system. It examines the physical principles governing the movement of blood, including its pressure, flow rate, and resistance. Understanding hemodynamics is crucial in medicine for diagnosing and managing various cardiovascular conditions. Key concepts include blood pressure, which is the force exerted by circulating blood on the walls of blood vessels, and cardiac output, the volume of blood pumped by the heart per minute. Blood viscosity, the thickness of blood, also plays a significant role in determining resistance to flow. Factors like the diameter and elasticity of blood vessels influence blood flow patterns. Deviations from normal hemodynamic parameters can indicate underlying pathologies such as hypertension, heart failure, or atherosclerosis. Medical interventions often aim to restore normal hemodynamic function by adjusting blood pressure, improving cardiac efficiency, or reducing vascular resistance. Diagnostic tools like echocardiography and Doppler ultrasound are used to assess hemodynamic variables non-invasively.
