Causes of Hypopnea, Hypoventilation, Hypoxia

Hypopnea means breathing that’s shallower or slower than what’s necessary to meet your body’s requirements, or underbreathing. Hypoventilation describes the situation wherein a reduced amount of air enters the alveoli in your lungs, resulting in hypoxia and hypercapnia. Hypoxia is the state of low oxygen in your blood, while hypercapnia means your blood contains too much carbon dioxide.

Hypocapnia’s low blood oxygen level, aka hypoxia, causes symptoms of:

Severe hypoxia can cause cerebral vasoconstriction, which may lead to quick episodes of dizzinessvisual disturbances and anxiety.

Holding your breath is a voluntary hypopnea condition of hypoventilation causing hypoxia. And some highly trained athletes may breath less than the untrained, yet they’re fewer breathes still meet their body’s needs.

Some health conditions that can cause involuntary hypopnea, hypoventilation and/or hypoxia are:

The consequences of hypopnea and hypoventilation can be an associated cause for other health conditions, such as:

And extreme case of hypercapnia can cause acidosismyoclonusseizures and respiratory failure.
