hemodynamics
Pronunciation: hee-moh-dy-NAM-iks
Study of blood flow and pressure within the cardiovascular system, fundamental to cardiac catheterization and critical care documentation.
Full Definition
The study of blood circulation and the forces involved in blood flow throughout the cardiovascular system, including measurements of pressure, flow, and resistance. Hemodynamic assessment is crucial in cardiac catheterization procedures, critical care management, and heart failure evaluation. Medical editors encounter hemodynamic data in invasive procedure reports, ICU monitoring documentation, and surgical case notes. Key parameters include central venous pressure, pulmonary artery pressure, cardiac output, and systemic vascular resistance. These measurements guide therapeutic interventions such as fluid management, vasoactive medications, and mechanical circulatory support decisions.
Usage
Usage note: Often used with specific pressure measurements; ensure units are clearly specified (mmHg, etc.).
In Context
- "Hemodynamic monitoring revealed elevated filling pressures consistent with heart failure." — Cardiac catheterization report
- "The patient's hemodynamics improved following diuretic therapy." — Critical care progress note
