Introduction: the Swan Ganz catheter remains the gold standard for hemodynamic evaluation. Newer techniques offer less invasive alternatives. The objective of this study is to compare the calculated cardiac index versus echocardiogram by measuring the same with the Swan Ganz catheter. Materials and methods: prospective, observational and comparative study of patients over 18 years old admitted to the Intensive Care Unit of the Carlos Andrade Marin Hospital, for one year. Patients older than 18 were included in shock with hemodynamic monitoring using Swan Ganz catheter and had adequate echocardiographic windows, a total of 13 patients at that time. Exclusion criteria: patients without proper monitoring without echocardiographic windows or Swan Ganz catheter. The comparison analysis of the means was performed by Student t test, and for correlation between techniques, the Pearson coeffcient was used. Results: there were 13 patients with a mean age of 57, the main diagnosis was sepsis. Comparison of the averages of the test values using the Student t value 0.220 P = 0.829 was obtained. The Pearson correlation index between the two techniques was 0.94 p <0.001. Conclusions: echocardiography estimated cardiac index was strongly correlated with cardiac index measurement by Swan Ganz catheter, the differences between the averages of the two measurements did not show statistical difference.
