Sleep
Polysomnography and other procedures are used to diagnose an array of sleep disorders, including sleep apnea, insomnia, restless leg syndrome, excessive sleepiness, narcolepsy, and other abnormal sleep behaviors. Diagnostic procedures include:
• Nighttime polysomnography for adults and children
• Daytime polysomnography for shift workers
• Multiple Sleep Latency Testing
• CPAP (Continuous Positive Airway Pressure) studies

Polysomnography
Polysomnography normally requires an overnight stay in one of our private suites. During this stay, while you sleep, you will be monitored for:
• Sleep Staging
• Eye Movement
• Nasal/Oral Airflow
• Chest and Abdominal Respiratory Movement
• Chin and Limb EMG
• EKG
• Pulse Oxymetry
Preparation
• Bring your pajamas, toothbrush and other morning essentials.
• For better sleep, bring your own pillow.
• Discontinue any medicinal sleep aids.
• On the day of the test, avoid caffeinated drinks such as coffee, tea and cola.
Testing
Your head is measured so that all electrodes fit comfortably and securely. Removable marks are made on your scalp where electrodes will be placed. Several others are placed on your chest and legs. Special jelly is applied to each electrode, which is then glued to your scalp and skin with an air blower. To measure your breathing, a plastic belt is placed around your chest. Wires are placed by your nose and mouth to monitor air flow during breathing, and a probe to measure the oxygen saturation of your blood is taped to your finger. Set-up may take over 30 minutes.
Multiple Sleep Latency Testing
The multiple sleep latency test records your brain waves (EEG), heart rate (EKG), muscle activity and eye movements.
Preparation
• Your hair should be clean, free of oil or hairspray, and dry.
• Meals and medication may be taken.
• On the day of the test, avoid caffeinated drinks such as coffee, tea, and cola.
Testing
Small electrodes will be attached to the scalp, around the eyes, under the chin, and on the shoulders. Before the recording, the technician may ask you to complete simple tasks such as looking left and right with your eyes only. During the test, you will lie in a prone position in a relaxed and quiet atmosphere to induce sleep. You will be monitored for about 20 minutes every two hours. You will be awakened and asked to stay awake until the next sleep time. During this time you may read, listen to music, watch television, or have a visitor.
The test takes about 7 hours and is often done following an overnight sleep study.
CPAP
CPAP delivers air into your airway. The mask does not breathe for you, but creates enough pressure when you inhale to keep your airway open.
