Continuous positive airway pressure (CPAP) therapy is considered the most effective nonsurgical treatment for snoring and obstructive sleep apnea. This study is performed the same as the Baseline study but with the addition of using a PCP machine to resolve the Sleep Apnea.
THE SLEEP DISORDER CENTER DOES NOT ADMINISTER OR STORE ANY MEDICATIONS
Before The Test
- Remain on all routine medication, unless otherwise instructed by the physician. Bring any medications that you may need while in the lab
- NO NOT take any naps the day of your study.
- No caffeine after 1pm. Please try to avoid all chocolate and limit your intake of caffeine to 1-2 cups of coffee, tea, or soda on the day of the procedure.
- Shower and wash your hair prior to arriving for the study. DO NOT use hair spray, oils, gels, or lotions on your hair or on your body.
- Bring sleepwear such as a two piece pajama set with sleeves or gym shorts and t-shirt.
- Showers are available in the morning after the sleep study is complete. Bring your own toiletries, hair dryers, etc. Towels and washcloths are available upon request.
- You should eat dinner before arriving a the sleep lab, but you may bring your own snack.
- Patients requiring nursing level of care, or unable to get into or out of bed without assistance must have someone stay with them all night.
- If you are currently using CPAP or BiPAP, bring the unit with you to the center.
- Please be prepared to leave the lab by 6 am.
During The Test
Sticky patches with sensors called electrodes are placed on your scalp, face, chest, limbs, and a finger. While you sleep, these sensors record your brain activity, eye movements, heart rate and rhythm, blood pressure, and the amount of oxygen in your blood.
Elastic belts are placed around your chest and belly. They measure chest movements and the strength and duration of inhaled and exhaled breaths.
Wires attached to the sensors transmit the data to a computer in the next room. The wires are very thin and flexible. They are bundled together so they don’t restrict movement, disrupt your sleep, or cause other discomfort.
If you have signs of sleep apnea, you may have a split-night sleep study. During the first half of the night, the technician records your sleep patterns. At the start of the second half of the night, he or she wakes you to fit a CPAP (continuous positive airway pressure) mask over your nose and/or mouth.
A small machine gently blows air through the mask. This creates mild pressure that keeps your airway open while you sleep.
The technician checks how you sleep with the CPAP machine. He or she adjusts the flow of air through the mask to find the setting that’s right for you.
At the end of the PSG, the technician removes the sensors.
