Abstract

The relationship between heart rate (HR) and oxygen consumption (V̇(O₂)) has been investigated in a sample of 20 low-risk, term neonates aged 14-48 hrs. Repeated, simultaneous measurements of HR and V̇(O₂) were performed on each neonate during each of three epochs ordered by increasing level of activity. A robust linear relationship was found between HR and V̇(O₂), with an average correlation of .90. Substantial variation was observed across individuals in the slope of the HR-V̇(O₂) regression line. This variation was curvilinearly related to ponderal index (PI), with low PI neonates having the shallowest and steepest slopes. These findings suggest that HR may provide a flexible, non-restrictive means of estimating neonatal V̇(O₂) but that the impact of prenatal growth history and postnatal growth performance on the estimation of V̇(O₂) from HR merits further investigation.
