Definitions:

Acidosis

A condition characterized by an excessive accumulation of acid or a significant loss of bicarbonate in the body, which can decrease blood pH.

Hyperventilation

Rapid or deep breathing that exceeds the body's need for oxygen, often leading to a decrease in carbon dioxide levels in the blood.

Hypoventilation

A state of insufficient ventilation leading to an increase in blood carbon dioxide levels, which can disrupt the body's acid-base balance.

Rebreathing

Rebreathing is the process of inhaling the air that has been exhaled, which can lead to an increase in carbon dioxide and a decrease in oxygen levels in the body.
