the temporary cessation of breathing while asleep, which occurs when the upper airway briefly becomes blocked (obstructive sleep apnea) or when the respiratory centers in the brain fail to stimulate respiration (central sleep apnea).
Keeping this in consideration, how is sleep apnea tested?
Tests to detect sleep apnea include:
- Nocturnal polysomnography. During this test, you’re hooked up to equipment that monitors your heart, lung and brain activity, breathing patterns, arm and leg movements, and blood oxygen levels while you sleep.
- Home sleep tests.
Hereof, what are the 3 types of sleep apnea?
There Are 3 Types of Sleep Apnea. Here are the key differences between obstructive sleep apnea, central sleep apnea, and complex sleep apnea.
What are the four stages of sleep in psychology?
Sleep has been traditionally divided into 4 categories: awake, light, deep, and REM sleep. Each one plays an essential role in maintaining your mental and physical health. Note: As you’re reading about sleep, you may also see the terms “NREM” or “Stages 1-4.” These are simply other terms for the phases of sleep.

They manifest as soon as we leave the transitionary state of sleep onset and enter the light phases of NREM sleep. From then on, they are generated regularly about every 3 to 6 seconds.
Which sleep stage is characterized by sleep spindles?
Sleep spindles are characteristic electroencephalogram (EEG) signatures of stage 2 non-rapid eye movement sleep. Implicated in sleep regulation and cognitive functioning, spindles may represent heritable biomarkers of neuropsychiatric disease.
