Charra [1.4K]

Hypoventilation can cause oxygen levels to fall too low, a condition called Hypoxia and carbon dioxide levels may rise too high, a condition called Hypercapnia.

Hypoxia is a state in which there is insufficient oxygen reaching the tissues of the body or a specific area of the body.

Generalized hypoxia, which affects the entire body, and local hypoxia, which affects a specific area of the body, are the two types of hypoxia.

Although fluctuations in arterial oxygen concentrations are frequently associated with clinical conditions, they can also occur naturally during severe physical activity or hypoventilation training.

A rise in carbon dioxide partial pressure (PaCO2) above 45 mmHg is referred to as hypercapnia.

The body produces carbon dioxide as a metabolic byproduct of its numerous cellular functions, and it has a number of physiological systems at its disposal to control its levels.
