Auscultate, Palpate and Tap : Time to Re‐Evaluate

Aim To determine the accuracy of current methods of heart rate (HR) assessment. Methods All participants palpated a simulated pulsating umbilicus (UMB), listened to a tapping rate (TAP) and auscultated a simulated HR (AUSC). A simulated HR of 54, 88 and 128 beats per minute (bpm) was randomised for all methods. Results Twenty-nine healthcare staff participated in this study. Correct assessment of HR of 54 bpm as being within the 0-59 range occurred in 17.2% UMB, 17.2% TAP and 31% AUSC and was obtained in 100 bpm by 96.6% UMB, 93.1% TAP, and 93.1% AUSC and was obtained in <10 seconds by 51.7%, 55.2% and 62.1%, respectively. Conclusion Current methods in assessing rates below 60 bpm are inaccurate and may overestimate HR. We recommend that these methods alone should not be relied upon in neonatal resuscitation and objective assessment of heart rate should be readily available at all newborn resuscitations.
