What is the effect of hypoventilation on oxygen delivery?

Hypoventilation refers to inadequate ventilation, which results in reduced air exchange in the lungs. As a result, the lungs do not take in enough oxygen or expel sufficient carbon dioxide. This leads to lower levels of oxygen in the blood (hypoxemia) and an accumulation of carbon dioxide (hypercapnia). Consequently, because oxygen is essential for cellular metabolism, diminished oxygen levels directly decrease the amount of oxygen delivered to the tissues, impairing their function.

By understanding this, one sees why the choice indicating that hypoventilation decreases oxygen delivery to the tissues is accurate. The other options either imply physiological responses that don't necessarily occur with hypoventilation or mistakenly indicate improvements in ventilation or gas exchange that conflict with the implications of insufficient ventilation.
