![]() Our group demonstrated that the median time to obtain the heart rate of very low birth weight newborns (<1500 g), by means of oximetry, was 67 seconds (interquartile range 50–93 seconds) ( Gandhi et al., 2013).ĮCG, which derives from the electrical activity of the heart, is not dependent on the circulation and so is less affected by the transitional state of the newborn. Importantly, this is a critical period when decisions, such as the need to begin PPV, must be made. However, the pulse oximeter, while helpful, does not provide a reliable heart rate in the first few minutes of life. With the inclusion of pulse oximetry for high-risk deliveries, all resuscitation teams can now monitor the heart rate continuously as long as the oximeter is functioning ( Kattwinkel et al., 2010). Even if the heart rate is being auscultated and manually tapped out by hand, it can be difficult for the leader of the resuscitation to recognize changes quickly. Previous NRP recommendations only required a snapshot of the heart rate every 30 seconds to determine whether it fell between two critical cut points (60 and 100 bpm) as defined in the guidelines.
