What to Expect From a Sleep Study
You will arrive at the Sleep Center about an hour before your bedtime. Technicians will place dime-sized sensors on different parts of your body. These measure heart rate, brain wave patterns, muscle activity, leg and arm movements and eye movement which indicate the stage of sleep. An elastic band holding gauges is strapped around your chest and abdomen to track movements of the muscles involved in breathing. Finally, a test called oximetry measures dips in the amount of oxygen in the blood, the hallmark of sleep apnea. People with sleep apnea actually stop breathing for several seconds, then strenuously gasp for air hundreds of times a night. More than 2.5 million Americans suffer from some form of sleep apnea.
The automated scanners of the Sleep Center produce a readout of each measurement, and these can be displayed next to one another so that one symptom or sign is easily correlated with another. For example, cessation of breathing usually coincides with a dip in the amount of oxygen in the blood, and both tend to occur when you are sleeping on your back.
