Correlation and Interchangeability of Venous and Capillary Blood Gases in Non-Critically Ill Neonates.

Background: Venous blood gas (VBG) is frequently used in the neonatal unit as alternative for capillary blood gas (CBG). However, studies reporting correlation are conflicting and data on interchangeability in neonates are lacking.

Objective: We investigated the correlation and interchangeability of the components between VBG and CBG in infants admitted to the neonatal intensive care unit.
