Sleep Disorder


Sleep studies are tests that watch what happens to your body during sleep. The studies are done to find out what is causing your sleep problems.Sleep problems include:

  • sleep apnea is when an adult regularly stops breathing during sleep for 10 seconds or longer. This may be caused by blocked airflow during sleep, such as from narrowed airways. Or it may be caused by a problem with how the brain signals the breathing muscles to work.
  • Problems staying awake, such as Narcolepsy.
  • Problems with nighttime behaviors, such as sleepwalking, night terrors, or bed-wetting.
  • Problems sleeping at night (insomnia). This may be caused by conditions such as restless leg syndrome, which is an intense urge to move the legs.

Sleep studies can also determine whether you have a problem with your stages of sleep. The two stages of sleep are non-rapid eye movement (NREM) and rapid eye movement (REM). Normally, NREM and REM alternate 4 to 5 times during a night’s sleep. A change in this cycle may make it hard for you to sleep soundly.


Sleep Endoscopy refers to a procedure performed under sedation in our MESIARC operation theatres which allows for an assessment of a patient’s airway adequacy (as well as any vibration or associated sounds made during respiration). By coming as close to a natural sleep state as possible, this assessment provides invaluable information in cases of suspected sleep apnea or disruptive snoring, which is often not gathered during a completely awake hospital visit. The specialist is also able to alter head and neck position, and provide airway support during the endoscopy, allowing for effective nonsurgical remedy of the sleep-associated airway narrowing. In cases where airway surgery is found to be indicated, this can often be performed at the same time as the diagnostic endoscopy.


In-Home Sleep Testing with CPAP Titration enables patients to undergo sleep studies from the comfort of their own bedroom for a more accurate diagnosis. Your doctor may recommend a sleep study if he suspects you are suffering from obstructive sleep apnea. To perform the in-home sleep testing, the patient will receive a portable monitor that measures activity while they are sleeping, and a CPAP (continuous positive airway pressure) device. The CPAP device is connected to the mouth, and it will automatically titrate, or adjust the amount of air pressure needed to breathe during sleep without causing apnea. For accurate test results, you must sleep for at least two hours on the night of your sleep testing. The next day, you return the monitor and the CPAP device to your doctor, who will interpret the results and create a customized treatment plan for your individual condition.
