This document discusses various problems that can affect newborns, including acidemia, acidosis, anoxia, asphyxia, hypercapnia, hypoxemia, and hypoxia. It defines each condition and provides details on their symptoms and causes. Acidemia refers to an increased acidity in the blood, while acidosis is a more general term for increased acidity throughout the body. Anoxia means a total lack of oxygen, and asphyxia is a deficient oxygen supply caused by abnormal breathing. Hypercapnia is an elevated level of carbon dioxide in the blood. Hypoxemia is low oxygen in the arterial blood, while hypoxia refers more broadly to insufficient oxygen supply at the tissue level
