What Is Sleep-Related Hypoventilation?
Sleep-related hypoventilation is one of four categories of sleep-related breathing disorders.
The others areobstructive sleep apneas, central sleep apnea syndromes, and sleep-related hypoxemia disorder.
The other types are rarer.
It is due to a gene mutation.
Sometimes it causes a person to stop breathing (respiratory arrest).
This disorder causes hypoventilation during sleep.
The term idiopathic typically refers to an unknown cause.
As such, there are still many questions related to this disorder that do not have answers.
What Does a Sleep Study Measure?
Polysomnography is a sleep study that records certain bodily functions and movements as you sleep or venture to sleep.
They both provide oxygen through a mask worn when a person is asleep.
The commonly used form of NIV isBiPAP, which is bi-level PAP.
This provides higher pressure when breathing in and lower pressure when breathing out.
A Word From Verywell
Sleep is essential for everybody.
It affects your ability to function and live your life.
However, sometimes you may notice difficulty sleeping or still feeling tired during the day.
