To achieve pulse oximeter signal acquisition in newborn resuscitations, current guidelines recommend attaching the pulse oximeter sensor first to the newborn and then to the extension cable. In a prospective, randomized trial of newborns ≥28 weeks' gestation born at a neonatal unit in India, investigators compared this method to one wherein the sensor was attached to the extension cable before delivery and was placed onto the newborn's palm or wrist after birth.
Of 149 infants (mean age, 33 weeks' gestation), median time from sensor application to reliable oxygen saturation and heart rate displays was significantly shorter in the oximeter-first group than the infant-first group (10 vs. 16 seconds). A similar time difference was found among t…
