hydrogen carbonate has been researched along with Fetal Hypoxia in 6 studies
Bicarbonates: Inorganic salts that contain the -HCO3 radical. They are an important factor in determining the pH of the blood and the concentration of bicarbonate ions is regulated by the kidney. Levels in the blood are an index of the alkali reserve or buffering capacity.
hydrogencarbonate : The carbon oxoanion resulting from the removal of a proton from carbonic acid.
Fetal Hypoxia: Deficient oxygenation of FETAL BLOOD.

The Apgar score is a simple method of quickly assessing the health and vital signs of a newborn baby created by and named after Dr. Virginia Apgar. Apgar testing assesses Appearance, Pulse, Grimace and Activity in a newborn and is typically done at one and five minutes after a baby is born, and it may be repeated at 10, 15, and 20 minutes if the score is low. The five criteria are each scored as 0, 1, or 2 (two being the best), and the total score is calculated by then adding the five values obtained. Agar scores of 0-3 are critically low, 4-6 are below normal, and indicate that the baby likely requires medical intervention, scores of 7+ are considered normal. The lower the Apgar score, the more alert the medical team should be to the possibility of the baby requiring intervention. Some components of the Apgar score are subjective, and there are cases in which a baby requires urgent medical treatment despite having a high Apgar score. (NCT01131260)
