Complete Question:

You volunteer for a sleep study and the researchers discover that your blood oxygen level drops many times during the night. It is likely that you have

A) sleep-onset insomnia.

B) REM behavior disorder.

C) narcolepsy.

D) sleep apnea.

Correct Option:

It is likely that you have "sleep apnea".

Option: D

Explanation:

Sleep apnea is a disorder which is identified by frequent stoppage and breathing start while sleeping. This is due to extreme relaxation of the throat muscles that hinder the normal breathing mechanism leading to reduced blood oxygen levels (recognized as hypopnea).

Throughout a sleep study, the patient's oxygen level is tracked with a pulse oxymeter connected to the hand, finger as well as other parts of the patient. An individual with SA will get a decreased amount of air in inhalation due to irregular breathing patterns while asleep.
