What is the average blood volume transferred in delayed cord clamping?

Delayed cord clamping is a practice in which the umbilical cord is not immediately clamped and cut after birth but is instead allowed to pulse for a brief period. This allows for additional blood, which is rich in red blood cells and other beneficial components, to flow from the placenta to the newborn. The average blood volume transferred during this process generally falls within the range of 25-35 ml/kg of body weight. This practice can enhance neonatal transition, improve iron stores, and support better physiological adaptation after birth.

Other ranges may be associated with varying practices or conditions, such as immediate clamping, which can affect the volume transferred. However, 25-35 ml/kg represents the commonly accepted average for delayed cord clamping in healthy newborns, as it effectively supports optimal outcomes for the infant.
