What condition is characterized by oxygen transport issues in infants?

The condition characterized by oxygen transport issues in infants is hypoxia, which refers to a deficiency in the amount of oxygen reaching the tissues. In infants, hypoxia can occur due to various factors such as respiratory distress, congenital heart defects, or as a result of maternal complications during pregnancy or childbirth.

While hemoglobinemia refers to the presence of excessive hemoglobin in the blood, it does not directly relate to the transport of oxygen but rather to increased plasma levels of hemoglobin. Hypercapnia involves an elevated level of carbon dioxide in the blood, which can occur when the respiratory system is not functioning properly but does not exactly reflect the issue of oxygen transport. Asphyxiation is a state resulting from a lack of oxygen, potentially due to obstructed airways, but it is a broader term that encompasses various causes of oxygen deprivation.

Thus, hypoxia is the most accurate description of the condition involving issues related to oxygen transport in infants.
