Methods: Theoretical analysis of the left ventricular pressure volume loop. Conclusions: The process of reanimation in the critically-ül population depends on indirect measurements of left ventricular performance factors, often derived from invasive maneuvers. Theoretical limitations frompulmonary artery catheter-derived calculations become ob-vious, and warrant the development ofnew methods that allow displaying left ventricularpressure-volume loop at the bedside.
