hemodynamics
Pronunciation: HEE-moh-die-NAM-iks
The study of blood flow characteristics including pressure, velocity, and resistance within the circulatory system.
Full Definition
Hemodynamics encompasses the physical principles governing blood circulation, including cardiac output, vascular resistance, and pressure gradients. In vascular medicine, hemodynamic assessment helps evaluate disease severity and guide treatment decisions. Key parameters include flow velocity, pressure measurements, and resistance calculations obtained through various diagnostic modalities. Understanding hemodynamics is essential for interpreting vascular studies and predicting treatment outcomes.
Usage
Usage note: Always singular when referring to the field of study; can be plural when referring to multiple flow parameters.
