Análisis matemático de la curva presión-volumen del ventrículo izquierdo

Abstract

Objective To present a practical approach to cardiac performance factors based upon physical and mathematical foundations that lie under the left ventricular pressure volume loop. methods Theoretical analysis of the left ventricular pressure volume loop. Conclusions The process of reanimation in the critically-ill population depends on indirect measurements of left ventricular performance factors, often derived from invasive maneuvers. Theoretical limitations from pulmonary artery catheter-derived calculations become obvious, and warrant the development of new methods that allow displaying left ventricular pressure-volume loop at the bedside.
