Why a sleep study?
- To identify sleep-related breathing disorders such as sleep apnea.
- To identify narcolepsy.
- To identify sleep behaviors that could be harmful to the patient or others.
- To set correct levels of CPAP (continuous positive airway pressure).
- If the patient has been treated for a sleep disorder but symptoms are not improving.
Why do I need to see my doctor first?
The Eastern Iowa Sleep Center is an Independent Testing Facility (IDTF) that is governed by standards which only allow testing to be scheduled after receiving a referral from your physician or a sleep medicine physician. This allows for evaluation of your health to determine if a sleep study is right for you.^ Return to top ^
What to expect
The Sleep Study is painless, no needles or injections. You are in a private room. Electrodes are gently pasted to your scalp, face and legs along with other sensors attached to your body.
- You will be able to move around in bed.
- You and your technician can communicate by intercom.
- A technician can disconnect the sensors if you need to use your private bathroom.
- You are free to read or watch TV until the Sleep Technician says "good night."
- An infrared light and camera in your room allows the technician to monitor your study.
- During your sleep your brainwave patterns, muscle tone, heart rate, breathing, oxygen and leg movements are monitored.
Our technicians will awaken you at the conclusion of the study which is typically 4-5 a.m. You may leave at that time.^ Return to top ^
