Sleep Apnea Test at Home

What is Sleep Apnea Study (PSG - PolysomnographySleep apnea study is the name of a test or study that is carried out when an individual is fully asleep. When you are asleep, the information about your sleeping status are recorded and the sleep disorders are defined, if any. Your physician evaluates your brain waves, oxygen level in your blood, heart rates and respiratory rate. Sleep has two stages.

  • REM (Rapid Eye Movement) sleep
  • Non-REM sleep

Brain activity is rather high during the REM sleep. Only the eye and respiratory muscles are active. This is the stage during which we dream.

Non-REM sleep process is the stage during which the brain activity slows down. A person without a sleep disorder passes from Non-REM sleep to REM sleep in every 90 minutes and goes through approximately 4-6 sleep cycles.

Monitoring the sleep cycles helps to define the potential problems in your regular sleep pattern by considering the reactions of your body against the changes in those cycles.

In which cases the sleep apnea study must be carried out?

Sleep apnea study is used for evaluating the findings of sleep apnea and diagnosing the sleep disorders. Sleep apnea is a sleep disorder characterized by pauses in breathing during the sleep. The symptoms are;

  • Daytime sleepiness
  • Loud and continuous snoring
  • Breath holding periods and dyspnea during sleep
  • Non-relaxing sleep

Sleep test is used for diagnosing some other sleep disorders as well.

  • Narcolepsy (deep sleep attacks during daytime)
  • Fainting due to sleepiness (seizure)
  • Witmaack-Ekboom’s Syndrome (Restless Legs Syndrome)
  • Chronic sleep withdrawal (sleep-onset insomnia)
  • REM sleep behavior disorders (sleepwalking)

National Heart, Lung and Blood Institute makes warnings regarding the fact that non-treated sleep disorders increase the risk of heart attacks, hypertension and paralysis.
