Perfusion index in healthy newborns during critical congenital heart disease screening at 24 hours: retrospective observational study from the USA.

ABSTRACT:

Objective

To describe the distribution of perfusion index (PI) in asymptomatic newborns at 24 hours of life when screening for critical congenital heart disease (CCHD) using an automated data selection method.

Design

This is a retrospective observational study.

Setting

Newborn nursery in a California public hospital with ~3500 deliveries annually.

Methods

We developed an automated programme to select the PI values from CCHD screens. Included were term and late preterm infants who were screened for CCHD from November 2013 to January 2014 and from May 2015 to July 2015. PI measurements were downloaded every 2 s from the pulse oximeter and median PI were calculated for each oxygen saturation screen in our cohort.

Results

We included data from 2768 oxygen sa
