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

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. ⸻ ⭐ Key Concepts Covered • Cardiac Output formulas • Stroke Volume determinants • Preload vs Afterload • Contractility changes • Fick equation for cardiac output • Vascular resistance and Poiseuille’s law • The relationship between resistance, pressure, and flow in cardiovascular physiology • Systemic vs pulmonary circulation • High-yield exam shortcuts from First Aid CVS Physiology #CardiacOutput #FirstAidCVS #Physiology #USMLEStep1 #MedicalSchool #CardiovascularPhysiology #PressureResistanceFlow #StrokeVolume #FickPrinciple #SVR #ExamPrep CHAPTERS: 0:00 - Introduction 5:42 - Stroke Volume 8:25 - Preload 9:46 - Contractility 18:50 - Cardiac Oxygen Demand 20:50 - Laplace’s Law 25:50 - Afterload 27:11 - Cardiac Output Equations 36:11 - Relationship between Resistance, Pressure and Flow 42:49 - Memory Drills
