What is Sleep Study/ Polysomnography?
Between thirty to forty-eight percent of Americans suffer from sleeping disorders such as insomnia, sleep apnea, and restless leg syndrome (RSL). A sleep study, also known as polysomnography, is conducted to diagnose these sleeping disorders.
“Insomnia is linked to high blood pressure and heart disease. Over time, poor sleep can also lead to unhealthy habits that can hurt your heart, including higher stress levels, less motivation to be physically active, and unhealthy food choices” – According to the CDC (Center for Disease Control and Prevention),
Often performed in sleeping centers or hospitals, a sleep study requires the patient to stay overnight to record their heart rate, body movements, and brain activity. Together, these factors will produce data that will reveal the specific cause of the patient’s disrupted sleeping cycle. This process will not only allow the doctor to detect the cause but also develop a treatment plan.
Understanding the process of sleep
Polysomnography specifically monitors the patient’s sleep stages to understand why their sleep is disrupted. To understand the mechanism of a sleep study it is important to first understand the normal process of falling asleep. As you begin to fall asleep, you enter the first stage called non-rapid eye movement (NREM) sleep in which your brain waves slow down significantly. Compared to the later stages, the movement of your eyes is halted in this stage. After the first few hours of NREM sleep, your brain waves start to pick up again with rapid eye movement (REM). A normal sleep process involves a cycle between NERM and REM every ninety minutes.
A disruption in this cycle is what causes a sleeping disorder. A sleep study is designed to detect these abnormalities.
Tests performed in a Sleep Study
There are multiple types of tests performed in a polysomnography (PSG) depending on the patient’s situation; this includes Diagnostic (routine) overnight PSG, Positive Airway Pressure (PAP) titration study, Split-night PSG with PAP titration, Multiple sleep latency test (MSLT), and Maintenance of wakefulness test (MWT). A diagnostic (routine) overnight PSG is a study that observes the different stages of your sleep cycle; this is most commonly used for a diagnosis. A Positive Airway Pressure (PAP) titration study is performed on patients who are already diagnosed with sleep apnea. It is used to determine the pressure setting of the PAP machine to best treat sleep apnea. A Split-night PSG with PAP titration is performed when the patient has severe sleep apnea; the procedure is split into two parts: a PSG and PAP therapy. An MSLT is a daytime sleep study consisting of five twenty-minute naps every two hours. This test is used to diagnose narcolepsy or other forms of hypersomnia (excessive sleepiness). An MWT is used to determine how well the patient can be awake under situations that make it easy to fall asleep. A sleep study can be performed for different purposes and disorders.
