Abstract
Hemodynamic monitoring is essential in the therapeutic guide of the critical patient. The pulsomagneto cardiac pressure gauge (PPC), is a non-invasive device, which records the cardiac output (CO) at the skin level and continuously. The objective of this work is determining the correlation of the GC measurement between the PPC system and the Fick Method in patients in the intensive care unit (ICU). It is a prospective, observational and longitudinal study. The CO was measured with both methods in 121 patients at admission, in addition to performing an analysis with Bland-Altman. As a Result of this work, the means of the CO by both methods did not show statistical differences p=0.05. The Sperman test reported a coefficient r=0.025, not significant p=0.77. The Bland-Altman analysis shows that the PPC overestimates the value of the GC at 3L. The results suggest that an imperfect standard was chosen. The pulse-magneto cardiac pressure gauge is operator-dependent. The PPC is a portable device for non-invasive monitoring of GC in critical patients.
