  • Small cup electrodes are attached to your scalp with the help of wires to measure brain activity.
  • Wire electrodes are taped to your face near the eyes and chin to show muscle activity. These electrodes are used to measure eye movements, thus giving clues to sleep stages.
  • Elastic belts are fastened around your chest and stomach to measure breathing effort.
  • A nasal cannula (clear plastic tubing) and small heat monitor to measure all breathing activity.

Sleeping during an In-lab Sleep Study

Having the capacity to rest serenely outside of one’s own bed while snared to a heap of wires seems like an unimaginable task. But it’s not. It rarely happens that a sleep study failed because of the patient’s lack of sleep. Regardless of the possibility that you surmise that you didn’t get any rest amid your overnight sleep pattern study, you might be astonished to find that you dozed a great deal more than you could recall. Furthermore, irrespective of the possibility that you truly didn’t get your fill of sleep amid your review, odds are you slept enough to provide a sufficient measure of information for the analysis.

What Happens After A Sleep Study?

In the morning, once you wake up, the monitors and wires are removed before you are allowed to go home or to work. Your sleep technician might not be able to comment on the obtained result because it is sent to the sleep specialist for evaluation.

In the morning the data collected is then scored and analysed by our trained Sleep Techs as per latest American Academy of Sleep Guidelines and standards .It is then interpreted by our Sleep Physician keeping in mind the clinical history. By midday the reports are ready and sent to you.If a sleep disorder is detected, possible treatments for the condition will be discussed by our Sleep Specialist or your doctor.
