Sleep Facts

Polysomnogram (PSG)

A polysomnogram, or PSG, is an overnight test that measures your sleep patterns. The technologist is specially trained to operate the sleep diagnostic equipment and remains all night in an adjacent control room. An intercom system is installed in each sleep room so you and the technologist may communicate

Split Night Study

Like the polysomnogram (PSG), sensors that measure brainwaves, eye movements, muscle tone, breathing patterns and blood oxygen levels are applied to your skin using paste and tape. Once you are asleep in your private room, the technologist carefully monitors the sleep diagnostic equipment for any sign of disrupted breathing during sleep. If interruptions in your breathing (known as sleep apnea) are seen, the technologist will apply CPAP during the second half of the test. (CPAP stands for Continuous Positive Airway Pressure) and is the most effective and widely used method of treating sleep apnea. The CPAP device does not breathe for you. You can breathe at a normal rate.

MSLT (Multiple Sleep Latency Test)

People may also experience excessive daytime sleepiness or fall asleep at inappropriate times. If you suffer from these symptoms your physician may send you to the sleep disorders center for the MSLT. The MSLT, or Multiple Sleep Latency Test, consists of five scheduled “nap” recordings during which you will be allowed to sleep for a brief period. The MSLT is conducted on the day following an overnight polysomnogram (PSG). During the PSG, sensors are applied to your skin with paste and tape to measure brain waves, eye movements, muscle tone, breathing patterns, and blood oxygen levels. During the naps, the technologist will monitor your sleep/wake patterns. Generally, the last naps are completed before 5:00 PM.

CPAP & BiPAP Titration Study

When you’ve had a previous polysomnogram and have been diagnosed with Sleep Apnea (OSA), your physician may have you return to the sleep center for a sleep study with CPAP. Sleep apnea is a sleep disorder characterized by interruptions in breathing. The CPAP does not breathe for you. At the start of a CPAP study, sensors will once again be applied to your skin and the technologist will monitor your brainwaves, eye movements, muscle tone, breathing patterns, and blood oxygen levels using special diagnostic sleep equipment. Before you fall asleep the technologist will fit you with the CPAP device.
