[Has the pH meter replaced the Apgar score?]
The introduction of measuring the pH appears to place it in competition with Apgar scoring because of its precision. A study of this which has been carried out has illustrated that there are two different criteria for assessing the state of the infant at birth. The usual agreement between pH values and Apgar scoring can be broken when clinical fetal distress has become established before metabolic equilibrium of the infant has become modified. In these circumstances the Apgar score will be bad while the pH will be good.
