Cardiac Output Made Easy | First Aid CVS Physiology (Variables, Determinants & Equations)

Описание: Unlock cardiac physiology with this high-yield First Aid CVS Physiology breakdown of Cardiac Output, including variables, determinants, and key equations you MUST know for exams like USMLE Step 1, INICET, PLAB, NRE and MBBS physiology.

In this video, we simplify:
• What is Cardiac Output?
• Major variables: Heart Rate, Stroke Volume, Preload, Afterload, Contractility
• Cardiac Output equations (CO = HR × SV)
• Fick Principle
• Determinants of Stroke Volume
• High-yield relationships between resistance, pressure, and flow (Flow = Pressure / Resistance)
• Systemic vascular resistance (SVR) and how it affects cardiac output
• Clinical correlations from First Aid

This lesson makes it EASY to understand cardiovascular physiology exactly as presented in First Aid for the USMLE—perfect for fast revision and exam scoring.
