hemodynamics

Pronunciation: HEE-moh-dy-NAM-iks

The study of blood flow and the forces involved in circulation, including pressure, flow, and resistance measurements.

Full Definition

Hemodynamics refers to the physical principles governing blood flow through the cardiovascular system, including the measurement and analysis of blood pressure, cardiac output, vascular resistance, and related parameters. In clinical cardiology, hemodynamic assessment is crucial for evaluating cardiac function, diagnosing cardiovascular disease, and guiding therapeutic interventions. Invasive hemodynamic monitoring through cardiac catheterization provides detailed information about intracardiac pressures, oxygen saturations, and calculated parameters such as cardiac index and vascular resistance. Non-invasive methods include echocardiography and bioimpedance monitoring. Understanding hemodynamics is essential for managing conditions such as heart failure, valvular disease, and cardiogenic shock.

Usage

Usage note: Use as singular noun despite plural appearance; specify invasive vs. non-invasive when relevant.
