Glossary Term
Hemodynamics
Definition
Hemodynamics refers to the study of blood flow, pressure, and circulation within the cardiovascular system. It involves the analysis of factors such as cardiac output, blood pressure, vascular resistance, and blood vessel compliance to understand how the heart and blood vessels work together to maintain adequate perfusion and oxygen delivery to tissues.
Relevance to the MedTech Industry
Hemodynamics is central to the development and evaluation of medical devices that monitor or support cardiovascular function. These include devices like hemodynamic monitors, pacemakers, ventricular assist devices, and blood pressure measurement systems. Understanding hemodynamics ensures that devices improve or maintain optimal blood flow and cardiovascular health.

Key Hemodynamic Parameters
Cardiac Output (CO): The volume of blood pumped by the heart per minute.
Blood Pressure (BP): The force exerted by circulating blood on vessel walls, typically measured as systolic and diastolic pressure.
Systemic Vascular Resistance (SVR): The resistance offered by blood vessels to blood flow.
Heart Rate (HR): The number of heartbeats per minute, affecting overall cardiac output.
Stroke Volume (SV): The volume of blood pumped by the heart with each beat.
