Free article Review Heart Rate Assessment Immediately after BirthEmily Phillipos et al. Neonatology. 2016. Free article AbstractBackground: Heart rate assessment immediately after birth in newborn infants is critical to the correct guidance of resuscitation efforts. There are disagreements as to the best method to measure heart rate. Objective: The aim of this study was to assess different methods of heart rate assessment in newborn infants at birth to determine the fastest and most accurate method. Methods: PubMed, EMBASE and Google Scholar were systematically searched using the following terms: 'infant', 'heart rate', 'monitoring', 'delivery room', 'resuscitation', 'stethoscope', 'auscultation', 'palpation', 'pulse oximetry', 'electrocardiogram', 'Doppler ultrasound', 'photoplethysmography' and 'wearable sensors'. Results: Eighteen studies were identified that described various methods of heart rate assessment in newborn infants immediately after birth. Studies examining auscultation, palpation, pulse oximetry, electrocardiography and Doppler ultrasound as ways to measure heart rate were included. Heart rate measurements by pulse oximetry are superior to auscultation and palpation, but there is contradictory evidence about its accuracy depending on whether the sensor is connected to the infant or the oximeter first. Several studies indicate that electrocardiogram provides a reliable heart rate faster than pulse oximetry. Doppler ultrasound shows potential for clinical use, however future evidence is needed to support this conclusion. Conclusion: Heart rate assessment is important and there are many measurement methods. The accuracy of routinely applied methods varies, with palpation and auscultation being the least accurate and electrocardiogram being the most accurate. More research is needed on Doppler ultrasound before its clinical use. © 2015 S. Karger AG, Basel. Similar articles

When do you assess a newborn's heart rate?Normally 120 to 160 beats per minute. It may be much slower when an infant sleeps. Breathing rate. Normally 40 to 60 breaths per minute.
How should a newborn's heart rate be assessed immediately after birth?During neonatal resuscitation, international resuscitation guidelines recommend assessing a newborn's HR by 'listening to the precordium with a stethoscope, feeling for pulsations at the base of the umbilical cord, or feeling the brachial or femoral pulses' [1].
How long should the nurse listen to count a newborn's heart rate?Assess heart rate carefully in a baby who is not active or who requires assisted ventilation. This is most easily accomplished by palpating a pulse at the base of the umbilical cord (Figure 9-13). Count the number of beats over 6 seconds and multiply this number by 10.
Does baby's heartbeat slow down after birth?Conclusions The median HR was <100 bpm at 1 min after birth. After 2 min it was uncommon to have a HR <100 bpm. In preterm infants and those born by caesarean section the HR rose more slowly than term vaginal births.
