Sleep Study Q & A

What is a sleep study?

A sleep study, or polysomnogram, is a comprehensive test that records multiple body systems during sleep. This typically includes monitoring:

• Brain waves (EEG): To assess sleep stages and identify disruptions.
• Heart rate and rhythm (ECG/EKG): To detect cardiac issues during sleep.
• Breathing rate and airflow: To identify breathing interruptions like those seen in sleep apnea.
• Blood oxygen levels (Pulse Oximetry): To check for drops in oxygen saturation.
• Eye movements (EOG): Helps determine sleep stages, particularly REM sleep.
• Leg and muscle movements (EMG): To detect conditions like Restless Legs Syndrome or Periodic Limb Movement Disorder.

This detailed information allows healthcare professionals to get a clear picture of your sleep patterns and diagnose underlying sleep disorders.

Types of Sleep Studies

In-Lab Sleep Study (Polysomnography)

Procedure: Conducted overnight in a specialized sleep center or hospital unit designed for comfort. Sensors are attached to your head and body to record data while you sleep. Trained technologists monitor you throughout the night.

Benefits: Provides the most comprehensive data for diagnosing a wide range of sleep disorders, including sleep apnea, narcolepsy, insomnia, periodic limb movement disorder, and parasomnias (like sleepwalking or REM sleep behavior disorder).

When it's used: Often recommended when complex sleep disorders are suspected or if an at-home test is inconclusive.

At-Home Sleep Apnea Testing

Procedure: You use a portable monitoring device in the comfort of your own home. Equipment is typically picked up from a clinic or delivered, with instructions for use. The device usually records breathing, oxygen levels, and heart rate.

Benefits: More convenient and often less expensive than in-lab studies. Highly effective (around 98% accuracy compared to in-lab studies) for diagnosing obstructive sleep apnea. Results are often available within a few days.

When it's used: Primarily used to diagnose or rule out obstructive sleep apnea in patients with a high likelihood of the condition. May not be suitable for diagnosing other sleep disorders or for patients with certain other medical conditions.

Common Sleep Disorder Diagnoses

Sleep studies can help diagnose various conditions, including:

• Sleep Apnea (Obstructive & Central): Characterized by repeated pauses in breathing during sleep.
• Insomnia: Difficulty falling asleep or staying asleep.
• Restless Legs Syndrome (RLS): An urge to move the legs, often accompanied by uncomfortable sensations.
• Narcolepsy: Excessive daytime sleepiness and sudden sleep attacks.
• Periodic Limb Movement Disorder (PLMD): Repetitive limb movements during sleep.
• Parasomnias: Including sleepwalking, night terrors, and REM sleep behavior disorder.
• Circadian Rhythm Disorders: Issues related to the body's internal clock, such as shift work disorder.

Preparing for Your Sleep Study

Whether your study is in a lab or at home, preparation is similar:

• Avoid Caffeine and Alcohol: Refrain from consuming these substances on the afternoon and evening before your study, as they can affect sleep patterns.
• Don't Nap: Avoid napping on the day of the study to help ensure you can fall asleep during the test.
• Bathing: Bathe or shower beforehand, but avoid using lotions, gels, hairsprays, or makeup, as these can interfere with sensor adherence. Also, avoid nail polish or fake nails if possible, as they can affect the pulse oximeter.
• Medications: Continue taking your regular medications unless specifically instructed otherwise by your doctor. Discuss all medications and supplements with your provider beforehand.
• Comfort: For in-lab studies, bring comfortable pajamas, toiletries, and perhaps a book or magazine. For at-home studies, follow the provided instructions carefully.

What to Expect During and After the Study

In-Lab: Technicians will attach sensors using adhesive. While it might feel unusual, most people adapt quickly. You can communicate with the monitoring staff if needed (e.g., to use the restroom). In the morning, sensors are removed, and you can go about your day.

At-Home: You'll apply the sensors and device yourself according to instructions before going to sleep. In the morning, you'll remove the equipment and return it as directed.

Results: Data from the study is analyzed by a sleep specialist. It typically takes a few days to a couple of weeks to receive your results. Your doctor will review the findings with you, discuss any diagnosis, and recommend treatment options if necessary.

Take Control of Your Sleep Health

Untreated sleep disorders can lead to serious health consequences, including cardiovascular disease, diabetes, depression, and an increased risk of accidents.
