Why is sleep study done?
Sleep studies are tests that watch what happens to your body during sleep and the studies are done to find out what is causing your sleep problems. Sleep problems includes problems taying awake such as nacrolepsy. There may be problems with nighttime behaviors, such as sleepwalking, night terrors, or bed-wetting. Sleep apnea is another problem where an adult regularly stops breathing during sleep for 10 seconds or longer and this may be caused by blocked airflow during sleep, such as from narrowed airways or it may be caused by a problem with how the brain signals the breathing muscles to work. Sleep studies can also determine whether you have a problem with your stages of sleep where the two stages of sleep are non-rapid eye movement (NREM) and rapid eye movement (REM).
Which are the most common sleep studies?
The most common slepp studies are polysomnogram where this test records several body functions during sleep, including brain activity, eye movement, oxygen and carbon dioxide blood levels, heart rate and rhythm, breathing rate and rhythm, the flow of air through your mouth and nose, snoring, body muscle movements, and chest and belly movement. Then another sleep study is Multiple Sleep Latency Test which measures measures how long it takes you to fall asleep. A video camera is used to record movements during sleep. Also Multiple wake test(MWT) measures whether you can stay awake during a time when you are normally awake.
How sleep study is done ?
Sleep studies are usually done by a trained sleep lab technician and are usually scheduled for evening and night hours that is from 10 p.m. to 6 a.m. in a special sleep lab where you will be in a private room, much like a hotel room. You will need to be at the sleep lab a few hours before the test so the technician can prepare you for the study where you will fill out a questionnaire about your sleep the night before and you will also be asked to fill out another form after the study about your sleep during the study.
