What term describes a blood pH above 7.4?

A blood pH above 7.4 indicates a condition where the blood is more basic than normal, which is referred to as alkalosis. The normal human blood pH typically ranges from 7.35 to 7.45. When the pH rises above this range, it signifies an excess of bases or a deficit of acids in the blood. This can occur due to various physiological conditions, such as hyperventilation, where excessive carbon dioxide is expelled, leading to a decrease in acid concentration.

In contrast, acidosis is the term used for a blood pH below 7.35, indicating an increase in acidity. Neutropenia refers to a condition characterized by an abnormally low level of neutrophils, a type of white blood cell that helps fight infections, and is unrelated to blood pH. Ischemia involves a reduced blood flow to tissues, which can affect oxygen and nutrient delivery but does not directly describe changes in blood pH. Understanding these definitions helps clarify the significance of the pH level in maintaining proper physiological conditions.
