A sleep test is becoming increasingly common these days owing to multiple kinds of sleep disorders that have been arising from time to time in a major part of the population. According to a recent survey, at least thirty to forty percent of the world’s population suffer from various sleeping disorders ranging from mild to acute. Therefore sleep test is crucial.
To have a polysomnography done, patients must visit a sleep clinic. This may be just a department in a big hospital or an entire chamber/institution dedicated to sleep study. Since sleep disorders can cause other body and hormonal imbalances, it is best to get it diagnosed at the earliest. However, the same kind of sleep study does not apply to all patients. There are different kinds of sleep studies modeled to suit different kind of patients.
Sleep Test 1: Polysomnogram Test
This test uses a device called a polysomnogram or PSG. This device is designed to note any irregularities in sleep patterns and helps understand what causes irregularities in sleep in the brain. This sleep study monitors breathing, muscle and brain activity while a patient is asleep to determine what may be causing a break in their sleep. This is useful for diagnosing sleep apnea, REM sleep disorder, narcolepsy, and other common sleep disturbances.
Sleep Test 2: Multiple Sleep Latency Test
Unlike the PSG test which only happens during one major sleeping phase, mostly at night, this MSLT is a full-day test having naps that are scheduled at intervals of five hours. This mostly reads how long a patient takes to fall asleep and once asleep, must be woken up after fifteen minutes. This sleep study is also useful for those with narcolepsy and hypersomnia.
CPAP Titration Test
This test is also conducted overnight, usually in a sleep clinic. Continuous positive air pressure is the full form of CPAP. This sleep study is most useful for those who have breathing problems while they are asleep.
Sleep Test 4: Split Night Study Test
This sleep study begins with a PSG test and ends with a CPAP tit-ration test. This test is usually conducted in a sleep clinic and is suitable for those who don’t want to keep coming back for prolonged periods and have very little time in hand. It is usually best for those diagnosed with OSA or obstructive sleep apnea.
All of us have experienced a disturbance in sleep at some point in time. While such disturbances are mostly temporary, in certain cases, they may continue for prolonged periods. Sleep disorders usually stem from some source of anxiety or stress that causes interference in sleep patterns because the brain is unable to relax fully. In case sleep disorders continue for weeks and months, without any apparent cause, it is best to get it diagnosed.
