Sleep study is an overnight observation of an individual’s sleep. This involves monitoring number of physiological parameters simultaneously like EEG (brain activity), the eye moments (EOG), the chin tone (EMG), breathing (nasal flow), breathing efforts, Oxygen level, heart rhythm (ECG).
Sleep is not a unitary phenomenon .It is divided into different stages like REM sleep (dreaming sleep) and Non REM sleep which is further subdivided into three stages.
The nature has made sleep like an orchestra with different notes at different points and diseases like Sleep Apnea disrupt this rhythm. This can be easily deciphered by a well conducted comprehensive sleep study.
Types of Sleep study
Level I : study being the gold standard where are all the above mentioned parameters are observed and attended to by a well-trained sleep technologist and the recordings are scored by scoring technologists and reviewed by Sleep physician who interprets the same and provides the final diagnosis and recommendation. The Sleep Specialist then discusses the report and advises the next line of treatment.
Level II : study is similar to level 1 but not attended by the sleep technologist and therefore there is a possibility of potential loss of data.
Level III : study involves monitoring of just two parameters mainly the breathing and the Oxygen level without monitoring the brain activity and the sleep.
Level IV : study is only monitoring the Oxygen level overnight.
In most situations Level 1 study is required however sometime the Sleep physician may conduct a simpler test.
Different forms of Sleep Studies
Diagnostic studies - In these only the diagnostic gear is used; this can be level 1 to level IV study.
Titration studies - which involve titration with CPAP or the BiPAP .This can be performed only in level 1 study setting.
Sleep studies are generally conducted in a split night format in which the first part of the night is the Diagnostic arm and in the latter half Therapeutic part where titration with CPAP is done. Split night studies are only possible with the level 1 format where a trained sleep technologist will conduct this study.
IS SNORING A DISEASE? CAN IT BE COMPLETELY CURED?
Computerized sleep lab and sleep analysis can find out if you or your spouse has a dangerous variety of snoring causing daytime sleepiness, high blood pressure and chance of strokes.
HOME SLEEP STUDY
Home sleep study is most appropriate for people who want to get the test done in the comfort of their home. it is suitable for diagnosing sleep apnea, restless leg syndrome and other sleep disorders. all our protocols for testing are based aasm (american academy of sleep medicine) standards. a detailed diagnostic report is prepared by a polysomnography technologist and validated by doctor .we provide best home sleep study at very reliable cost.
• Services delivered at your door step.
• Protocols for testing based on AASM ( American Academy of Sleep Medicine) standards.
• Detection of apneas ( central, obstructive, mixed), hypopneas, rera’s, flow limitation and snoring.
• Detection of neurological and cardiac abnormalities in sleep.
• Detection of limb movements.
• Accurate staging of sleep and sleep architecture.
Goals of treatment
• Restore regular breathing during sleep.
• Relieve symptoms such as loud snoring and daytime sleepiness.
• Treatment may improve other medical problems linked to sleep apnea, such as high blood pressure. Treatment also can reduce your risk for heart disease, stroke, and diabetes. Lifestyle changes and/or mouthpieces may relieve mild sleep apnea. People who have moderate or severe sleep apnea may need breathing devices.
If you continue to have daytime sleepiness despite treatment it’s important to ensure that you are getting enough sleep; adults should get at least 7 to 8 hours of sleep; children and teens need more.
