Hypoventilation
Caused by...
Carbon dioxide:
Whilst either slow or shallow breathing may occur with hypoventilation, the rate or depth of breathing is not diagnostic, since hypoventilation, by definition, occurs if there is an increase in carbon dioxide levels.

If the body retains too much carbon dioxide, due to impaired respiratory function, the body’s pH drops and become more acidic, creating Respiratory Acidosis.

Alveolar hypoventilation exists when the arterial partial pressure of carbon dioxide (PaCO2) exceeds the normal upper limit of 43 mmHg.
