What is the normal pH range for venous blood in term newborns?

The normal pH range for venous blood in term newborns is indeed between 7.28 and 7.40. This range is important for maintaining homeostasis, and it reflects the internal environment of the body, ensuring optimal conditions for cellular functions.

In term newborns, venous blood pH can vary slightly due to factors like transition from fetal to neonatal circulation, respiratory adjustments post-birth, and metabolic activity. The selected range allows for some variability while still being within the parameters that indicate a normally functioning biological system.

A pH below this range could indicate acidosis, while a pH above might suggest alkalosis, both of which could prompt further investigation or intervention in a clinical setting. Understanding these normal values aids healthcare professionals in recognizing potential complications and managing the neonate's health effectively.
