Does pulse oximetry accurately measure heart rate compared to ECG in stable preterm infants in the neonatal intensive care unit?
Mean Difference: -0.4
Pulse oximetry provides an accurate measurement of heart rate in stable preterm infants in the NICU, even when signal quality or perfusion is low.
Pulse oximetry agrees closely with ECG for heart rate in stable preterm infants; leaves open validation during instability or poor signal quality.
AIM: To determine the accuracy of pulse oximetry measurement of heart rate in the neonatal intensive care unit. METHODS: Stable preterm infants were monitored with a pulse oximeter and an ECG. The displays of both monitors were captured on video. Heart rate data from both monitors, including measures of signal quality, were extracted and analysed using Bland Altman plots. RESULTS: In 30 infants the mean (SD) difference between heart rate measured by pulse oximetry and electrocardiography was -0.4 (12) beats per minute. Accuracy was maintained when the signal quality or perfusion was low. CONCLUSION: Pulse oximetry may provide a useful measurement of heart rate in the neonatal intensive care unit. Studies of this technique in the delivery room are indicated.
