Polysomnogram – If there is a problem with your breathing during sleep, then a physician will recommend that you have an overnight sleep study featuring a polysomnogram. Electrodes will be attached to your head and body by a technician who will monitor and record your brain waves (EEG), heart rate/rhythm (ECG), breathing patterns and blood oxygen saturation during sleep. They will also record eye, arm and leg movement. These results will reveal if you have OSA, and the severity of the problem.
Comprehensive Sleep Evaluation & Follow Up – Patients determined to have OSA may be asked to return to the sleep center for a second polysomnogram and a continuous positive airway treatment while they sleep, which is called a CPAP study. CPAP/BiPap Titration is a common treatment for OSA. Delivered through a mask worn over the nose, it allows air to blow into the back of the throat, keeping the airway open. This allows the OSA patient to keep breathing while they sleep.

MSLT/Nap Study – The Multiple Sleep Latency Test (MSLT) is a nap study used to determine how quickly one falls asleep in quiet situations during the day. The MSLT is the standard way to measure your level or severity of daytime sleepiness. Excessive sleepiness is described as when you are sleepy at a time and place when you should be awake and alert. During this test, we will ask you to attempt to fall asleep at approximate 2 hour intervals from 9am to 5pm, measuring the speed at which you fall asleep and the type of sleep. Sleep latency is a good indicator of the degree of your excessive daytime sleepiness, and the kind of sleep you obtain will indicate whether or not you have narcolepsy.
