Explanation of Services:

 What happens during a sleep study and what are all those wires?

Sleep studies (also called a Plysomnogram or PSG) look at several “channels” of information during sleep.   We typically collect a minimum of 6 hours of data, which is then “scored” by looking at each 30 second period of sleep throughout the night.

We monitor brain waves, oxygen levels, heart rate, breathing and leg movements, gathering information to diagnose your particular sleep problem.

When you arrive you will change into your night clothes (we recommend shorts and a loose fitting tee shirt).   You will then be hooked up using a mild paste to help the electrodes adhere.  It does feel strange at first but because the hallmark symptom of most sleep disorders is sleepiness, patients usually fall asleep with little problem.

In the morning you will be awakened when we have acquired the necessary data and you may go home.  The information is analyzed and interpreted and then sent to your ordering physician within 48-72 hours, though more urgent analysis can be obtained on physician request. You may be asked come back for other testing depending on the results of your study.

CPAP Titration may be initiated if you have significant sleep apnea at either your initial test or on a follow-up evaluation. CPAP stands for Continuous Positive Airway Pressure.  Room air is condensed and delivered through a mask to act as an airway “splint” to help keep your airway open and keep you breathing all night (without snoring!)

 An MSLT test (Multiple Sleep Latency Test) may be ordered if your doctor suspects Narcolepsy.  After a PSG to ensure you have had a good night’s sleep, a next day study consisting of four to five 15-35 minute “naps” takes place at intervals throughout the day. 

 Treatment of your sleep disorder will depend on your diagnosis.  For some patients, simple behavior modifications such as weight loss or reducing caffeine may be recommended.  For others, medication, special medical devices, special dental devices, or surgical evaluation may be necessary.
