What is the normal pH range for umbilical artery blood?

The normal pH range for umbilical artery blood is indeed between 7.20 and 7.29. This range reflects the acid-base balance in a healthy fetus during labor and delivery. A pH within this range indicates that the fetus is adequately oxygenated and there are no significant acid-base disturbances occurring due to fetal distress or hypoxia.

Maintaining appropriate pH levels is crucial because deviations can signal fetal distress. A pH below 7.20 may indicate acidosis, which can be a result of inadequate oxygen supply, while a pH above this range typically suggests alkalosis, which is less common in a fetal setting. Thus, recognizing this normal pH range allows healthcare providers to assess and monitor fetal well-being effectively. Understanding these parameters is vital for making timely and informed clinical decisions during labor and delivery.
