Cardiovascular Physiology for Anesthesia Technicians

Cardiovascular physiology helps anesthesia technicians and technologists understand how the heart and blood vessels maintain circulation and deliver oxygenated blood throughout the body. These principles provide a foundation for understanding blood pressure, cardiac monitoring, fluid administration, and hemodynamic changes during anesthesia.

This lesson covers cardiac output, heart rate, stroke volume, preload, afterload, contractility, vascular resistance, blood pressure, and the cardiac cycle. Clinical examples connect these concepts with ECG monitoring, arterial blood pressure, fluid status, vasoactive medications, and hemodynamic monitoring in the anesthesia environment.
