Baan’s Equation: Conductance-Based Pressure–Volume Loops

by

Baan’s equation forms the mathematical and physiological foundation of conductance-based pressure–volume (PV) loop technology. This method allows real-time, beat-to-beat measurement of left ventricular volume inside the intact, beating heart—making it one of the most powerful tools for studying cardiac mechanics, ventricular-arterial coupling, and contractility. Traditional PV measurements relied on imaging or indicator dilution techniques, which … Read more

Enhancing Real-Time Cardiac Monitoring with Baan’s Equation and PV Loop catheter Technologies

by

Introduction Advancements in cardiac monitoring technology have transformed how clinicians assess heart function in real-time, particularly in intraoperative and critical care settings. Two pivotal innovations—Baan’s Equation and PV Loop catheter technologies—offer a synergistic approach to improving hemodynamic evaluation. Baan’s Equation provides a mathematical model to estimate ventricular volume, while the PV Loop catheter enables real-time … Read more
