Enhanced Neonatal Pulse Oximetry Sounds for the First Minutes of Life: A Laboratory Trial.

Objective: Auditory enhancements to the pulse oximetry tone may help clinicians detect deviations from target ranges for oxygen saturation (SpO) and heart rate (HR).

Background: Clinical guidelines recommend target ranges for SpO and HR during neonatal resuscitation in the first 10 minutes after birth. The pulse oximeter currently maps HR to tone rate, and SpO to tone pitch.
