Correlación del índice de perfusión con la repercusión del conducto arterioso en prematuros

The ductus arteriosus is a necessary structure in fetal circulation, and its patency can produce hemodynamic alterations. The diagnostic gold standard is echocardiography, not always available. In the neonatal intensive care unit (NICU) they have pulse oximetry that measures perfusion index (PI), which could be used as a diagnostic tool in hemodynamic significant patent ductus arteriosus (HSPDA).To correlate the perfusion index increment (ΔPI)...
