Labor Day Weekend

An umbilical artery arterial blood gas is obtained in a 34 week newborn right after a prolonged delivery to a G1P1 30 year old mother. The ABG reads: pH 7.25, pCO2 50 mmHg, HCO3- 23 mEq/L, and base excess -3 mEq/L.

Challenge: What's your interpretation?

These are, in fact, within the normal range of an umbilical artery ABG for a preterm newborn.
