Rest easy with help from Johnston Health in Smithfield, home to a sleep lab accredited by the Accreditation Commission for Health Care. Adults can take a sleep study, or polysomnogram, to learn more about their condition and start the journey to more satisfying sleep.
We are taking every precaution to keep our sleep study patients safe. Below are a list of safety procedures we have in place.
In Lab Studies
- Patients are screened 3 times before undergoing testing. Once when scheduled, once on the day of testing when their appointment is confirmed and then upon arrival to the lab.
- Staff are gowned, gloved and wear N-95 masks and goggles with all patients. Patients are asked to wear masks at all times while in the facility except when sleeping.
- If CPAP units are used, disposable hoses and masks or nasal pillows and filters are thrown away after each patient. The exterior of the unit is wiped down with approved cleaning solution and filters are replaced with each use.
- In our patient rooms, all bedding is changed after the patient leaves and replaced with newly laundered linen. All surfaces in close proximity to or in direct contact with patient are wiped down with approved disinfectant.
Home Sleep Testing
- The patient is called to set up an appointment to come in to the hospital to pick up the equipment and receive instructions. Patients are screened for COVID at the time they are registered and the day of the appointment.
- Once the patient returns the equipment, disposable supplies are discarded and the home testing equipment is disinfected with an approved solution.
- New disposable supplies are placed with the unit for the next patient.
Do I Need a Sleep Study?
You may benefit from a polysomnogram if you have sleep disorder symptoms, such as:
- Daytime sleepiness
- Depression or irritability
- Lack of energy
- Loud snoring
- Morning headaches
- Poor work performance due to fatigue
- Restless sleep
- Trouble concentrating or remembering
What to Expect at the Sleep Lab
Spend your usual sleeping period in one of our lab’s private, comfortable rooms with a full-size bed, shower, and cable TV. Feel free to bring your favorite pillow or use one of ours.
A registered sleep technologist will put sensors on your head and body to measure the following as you sleep:
- Blood oxygen level
- Brain waves
- Eye and leg movements
- Heart rate
A video camera will also record your movements throughout the study.
After the study, you can return to your everyday activities.
CPAP Titration for Sleep Apnea
If you show signs of sleep apnea during the study, the technologist may wake you and provide a continuous positive airway pressure (CPAP) mask for you to wear the rest of the night. Or, you may need to schedule another appointment for a full-night CPAP study.
In either case, the technologist will adjust the airway pressure as you sleep to find the setting that lets you breathe steadily. Then, you can use a CPAP device at home to prevent sleep apnea.
Daytime Nap Study
You may benefit from a daytime nap study if you report symptoms of narcolepsy (suddenly falling asleep during the day). Also called a multiple sleep latency test, this daylong study includes five scheduled naps divided by two-hour breaks. A technologist will measure how long it takes you to fall asleep each naptime.
Prepare for Your Study
To get the most accurate results, follow these steps on the day of your study:
- Do not consume coffee, tea, soda, chocolate, or other products with caffeine after noon.
- Do not drink alcohol.
- Do not nap.
- Shower and wash your hair and skin, but avoid hair products other than shampoo. Clean hair and skin help the sensors attach better.
- Bring all medications you normally take, except any drugs your doctor said to avoid before the study.
Home Sleep Study
Sometimes, if your doctor wants to check for sleep apnea, you may take a convenient home sleep study. You’ll learn how to use a small monitor that attaches to sensors on your finger, nose, and chest. The monitor records your vital signs and movements overnight as you sleep in your own bed.
Our board-certified sleep medicine doctor will review the results and send a report to your primary care provider. Your primary care provider will share it with you and, if necessary, recommend treatments, lifestyle changes, and tips for better sleep.
