Polysomnogram
What is a Polysomnography (PSG)?
Polysomnography (PSG) is an overnight sleep study test used to diagnose sleep disorders.
A Polysomnography Test, also known as PSG, monitors your different stages and cycles of sleep to determine if or when your sleep patterns are interrupted and why. The sleep study technician will place sticky gel patches, with sensors called electrodes, on your scalp, face, chest, limbs, and a pulse oximetry sensor on your finger.
While you sleep, these sensors record your brain and sleep activity, eye movements, heart rate and rhythm, leg movements, and the amount of oxygen in your blood.
Do you have signs of Sleep Apnea?
You may need a split-night sleep study if you show signs of sleep apnea, which means the technician will record your sleep patterns for the first half of the night. At the start of the second half of the night, the technician wakes you to fit a CPAP (continuous positive airway pressure) mask over your nose and/or mouth.
A small machine gently blows air through a tube that is connected to the mask; this creates mild pressure that keeps your airway open while you sleep. The Aylo Health technician will monitor your sleep with the CPAP machine. The technician adjusts the flow of air through the mask via the computer system to find the setting that’s right for you.

Should your test results reveal the need for durable medical equipment (DME) or positive airway pressure (PAP) devices and supplies, our Sleep Center offers several options for you depending on severity.
The staff here are so helpful and make sure you understand everything they are doing when doing a sleep study. Once they issue equipment, they show you how to use everything and are so patient. I recommend them for anyone who is needing a sleep study done.

What to expect at your Polysomnography Test
This sleep study is performed in the comfort our Sleep Center in McDonough, GA. In addition to the sticky gel patches on your scalp, face, chest, and limbs — two stretchable belts are placed around your chest and belly to measure chest movements and the strength and duration of inhaled and exhaled breaths. Wires are attached to the sensors that transmit the data to a computer in the Sleep Tech Monitoring Area.
The wires are very thin and flexible; they are bundled together so they don’t restrict movement, disrupt your sleep, or cause other discomforts. You are able to disconnect these wires if you need to visit the restroom. At the end of the sleep study, the technician removes the sensors unless you are having a daytime sleep study, such as a Multiple Sleep Latency Test.
Frequently Asked Questions
Are parents allowed to spend the night with their minors during their sleep study?
Yes, in fact, parents of minors getting a sleep study are required to spend the night with their child. At Aylo Health, we have a very nice family room to accommodate parents who are assisting their children, and we can offer you the opportunity to sleep in the same room as the minor (if preferred).
