Sleep Study Process

Polysomnography at a Clinic

Imagine spending a night at a sleep clinic, surrounded by wires and monitors, while a team of experts scrutinizes your every move. This is the essence of polysomnography, the gold standard for diagnosing sleep disorders.

During polysomnography, electrodes are placed on various parts of your body to measure brain activity, eye movements, muscle tone, heart rate, and breathing patterns. Additionally, you may wear a nasal cannula to monitor airflow, a fingertip sensor to measure blood oxygen levels, and a chest strap to gauge respiratory effort.

It may feel strange and uncomfortable, but fear not, as the insights gained from these readings will provide invaluable information about your sleep health.

Multiple Sleep Latency Testing

For those who struggle with excessive daytime sleepiness, multiple sleep latency testing (MSLT) is a crucial component of the sleep study process. MSLT measures how quickly you fall asleep in a controlled environment during the day.

This test consists of a series of naps in a quiet and dimly lit room, typically conducted every two hours. A technician will monitor your brainwaves to determine the onset of sleep and assess your level of daytime sleepiness.

MSLT helps identify conditions such as narcolepsy and idiopathic hypersomnia, enabling doctors to develop personalized treatment plans.

In-Home Sleep Apnea Tests

Not everyone has the luxury of spending the night at a sleep clinic. Thankfully, there are in-home sleep apnea tests available for those with suspected sleep apnea.

These tests involve the use of portable devices that measure breathing patterns, oxygen levels, and other vital signs while you sleep in the comfort of your own bed. Although not as comprehensive as clinic-based polysomnography, these tests can provide a preliminary diagnosis for obstructive sleep apnea.

If you receive a positive result, further evaluation at a sleep clinic may be necessary to confirm the diagnosis and determine the severity of the condition.
