Correlation of Cardiac Output Measurement by Goal-Directed Echocardiography Performed by Intensivists vs Pulmonary Artery Catheter

Abstract: Measurement of cardiac output (CO) is often performed in the assessment of critically ill patients with undifferentiated shock. Doppler echocardiography has been shown to be a reliable method for estimating cardiac output when images are acquired by cardiac sonographers and interpreted by cardiologists. However, few studies have assessed the accuracy of CO measurements by Doppler echocardiography performed by non-cardiac intensivists. The purpose of this study was to compare the accuracy of CO measurements by … Show more

“…Tanto en la Universidad Nacional como en la Universidad del Norte, la formación en ultrasonido se ha fortalecido con la investigación clínica. Reportes de casos, cohortes, estudios transversales de validez diagnóstica, entre otros, se han publicado en revistas nacionales e internacionales (5,19,20,(22)(23)(24). Esto se suma al acervo de evidencia mundial que permite reconocer hoy el ultrasonido clínico como una herramienta revolucionaria tanto para el médico, como para los pacientes e incluso para los sistemas de salud.…”

“…Bedside ultrasound emerges as a simple, accessible, and cost-effective tool for hemodynamic monitoring, showing good correlation and approximation to the PAC [ 4 , 5 ]. Ultrasound allows estimation of CI and filling pressures [ 6 10 ], although there is limited evidence for calculating SVR using this method. Drawing on the Windkessel principle and the behavior of the arterial compartment, the assessment of resistance indexes (RI) in different vascular beds has been proposed as a potential estimator of systemic vascular resistance index (SVRI) [ 11 13 ].…”
