The perfusion index histograms predict patent ductus arteriosus requiring treatment in preterm infants

Conclusion: We conclude that a patent ductus arteriosus requiring treatment in preterm infants ≤ 29 weeks GA was associated with significant fluctuations between a low PI<  0.4 alternating with a high PI>  2, reflecting the dynamic nature of hsPDA shunt volume. PI variability may be an early marker of hsPDA.What is Known:•The perfusion index is a continuous underutilized parameter provided by pulse oximetry to assess the peripheral perfusion.•The perfusion index helps predict conditions with hemodynamic instability.What is New:•The perfusion index assessed as daily histogram trends can predict patent ductus arteriosus requiring treatment.
