Prospective Evaluation of a Multibeat Analysis Cardiac Index Estimation in Patients With Cardiogenic Shock
Main finding · Cardiac indexResult — go to the resultMean difference (bias ± SD) 0.20 ± 0.47 L/min/m²Authors' conclusion
Cardiac index-MBA is not interchangeable with CI-TD. However, CI-MBA provides reasonable correlation and clinically acceptable trending ability compared with CI-TD.
