These tests are done to record body activities at the time of sleep and are known as sleep study. These tests assist to identify sleep problems. The gold standard to find out obstructive sleep apnoea is known as Polysomnography. ‘In- lab polysomnography’ is recommended for those patients who cannot find out their sleep problems through ‘in-home studies’ and complains of unrefreshed sleep. These sleep studies can assist to find out or diagnose following problems-
Breathing disorders while sleeping, for example-sleep apnoea ( Cessation of breathing), Convulsion during sleep
Involuntary/uncontrolled movement of the limbs during sleep, Problem of falling and maintaining sleep. Insomnia - due to depression, anxiety or stress. Daytime dizziness or narcolepsy, Sleep problems like- bad dreaming, bed wetting and sleep walking. Teeth grinding while sleeping. Altered sleep pattern for the night shift workers, Stages of sleep problem determination.
At-home sleep study:
A simple form of sleep study can be done at home.
Different body functions are recorded through polysomnography at the time of sleep which include- eye movement, brain activity, heart rate and rhythm, level of oxygen and carbon di oxide in blood, chest and abdomen movement, respiratory rate and rhythm, flow of air through mouth and nose, muscle movement, snoring.
Multiple Sleep latency Test(MSLT):
It evaluates several nap opportunities in single day. Moreover, it also determines the time duration of the person’s falling into sleep. This also finds out whether REM sleep pattern comes up or not at the time of sleeping. This procedure is normally done instantly after the overnight study.
Test for maintenance of wakefulness (MWT):
MWT determines the person’s ability to be fully awake during the time when he or she is usually awake. To determine one’s maintenance of wakefulness as well as sleep pattern is a highly concerned issue as they are related with severely fatal conditions, like- diabetes, hypertension, depression, heart diseases, stroke and many more chronic health conditions.
So in this case polysomnography would be a great help. After recording the full night’s sleep the technologist will interpret the collected date and the patient will be advised the proper therapy suitable for his condition-these might include-oxygen or CPAP(continuous positive airway pressure) ventilation or might be solved with medication only.
Preparation instructions for the patients who are willing to do sleep studies will be provided by our staff at the premises or can be asked over phone after confirming the appointment.
