Tic Tac Toe Method Arterial Blood Gas (ABG) Interpretation for Nurses Acidosis usually presents itself as decreased blood pH and increased base deficit. 7.35-7.45. pH < 7.35 indicates ACIDOSIS (ACID) The levels determine if the baby has acidosis, a condition caused by the overproduction of acid in the blood. However, when umbilical cord occlusion associated with terminal bradycardia is the underlying pathology, the umbilical artery sample typically has a worse base deficit than in the umbilical vein sample. Obstet & Gynecol 2010; 1(9): WMC00694, Mokorami P, Miberg N, Olofsson P. An overlooked aspect on metabolic acidosis at birth: blood gas analyzers calculate base deficit differently. Delay in clamping may result in significant change in acid-base parameters; the longer the delay, the greater is the change. Evaluation of the newborn's blood gas status - OUP Academic National clinical guidelines in the UK [26], endorsed by the Royal College of Obstetricians and Gynaecologists, suggest a selective approach, in stating that Paired cord blood gases do not need to be taken routinely. This has medico-legal significance for resolving disputes about the cause of brain damage sustained at birth [11]. I am so grateful that I was lucky to pick Miller & Zois. TABLE I: Median and centile ranges for umbilical-cord blood gas and lactate values [1]. Early Human Development 2010; 86: 336-44, Kurinczuk J, White-Koning M, Badawi N. Epidemiology of neonatal encephalopathy and hypoxic-ischemic encephalopathy. Eur J Obstet Reprod Biol 2012; 162: 21-23, Armstrong L, Stenson B. Delay in clamping by as little as 45 seconds after birth results in significant change in acid-base parameters [13-15]; the longer the delay, the greater is the change [16, 17].

When the baby is born, the umbilical artery briefly retains information about the baby's current condition, referred to as blood cord gases. Below, the venous and arterial cord gases each have been "normalized" to a \(P_{CO_{2}}\) of 38 and 49 mmHg (the mean normal venous and arterial \(P_{CO_{2}}\)), respectively, as is done artificially by the equation used to calculate the base deficit in blood gas analyzers.
