WebExpected pH = 7.4 – [ 0.003 x (PaCO2-40)] If pH is below the expected value in acute respiratory acidosis, there is concomitant metabolic acidosis present. If it is above the … WebThe most important measurements in a blood gas test for evaluating a baby’s current condition and prognosis are the pH and the base deficit. Some experts define fetal acidemia as a pH of less than 7.1. However, there may be negative consequences even with a higher pH (this is discussed more below; see “Severity of acidosis and brain damage”).
