Reliability of Pulse Oximetry during Cardiopulmonary Resuscitation in a Piglet Model of Neonatal Cardiac Arrest

Abstract

Pulse oximetry showed increased bias and decreased accuracy and precision during CPR in a model of neonatal cardiac arrest. We recommend further studies to clarify the exact mechanisms of these false readings to improve reliability of pulse oximetry during the marked desaturation and hypoperfusion found during CPR.
