In Lab Sleep Testing

4 Better Sleep Centers are accredited sleep diagnostic facilities that conduct in lab sleep tests for evaluation of sleep disorders. A patient spends the night in one of our specialized sleep centers. Here’s what a patient can expect during an in-lab sleep study:

• Preparation: You arrive at the sleep lab, where you’ll be in a private room resembling a hotel room. Electrodes (small pads or patches) are placed on your head and body using a mild adhesive. These electrodes record various parameters, including brain activity, eye movement, oxygen levels, and snoring.
• Monitoring: Throughout the night, the following aspects are closely monitored:
  • Brain Waves: Electroencephalography (EEG) records brain wave patterns.
  • Oxygen Levels: Pulse oximetry measures blood oxygen saturation.
  • Heart Rate and Breathing: Electrocardiography (ECG or EKG) tracks heart rate and rhythm.
  • Muscle Activity: Electromyography (EMG) monitors muscle movements.
  • Eye Movement: Electrooculography (EOG) detects eye movements during different sleep stages.
• Sleep Stages: The study captures data on your sleep cycles, including rapid eye movement (REM) sleep and non-REM stages. This information helps diagnose conditions like sleep apnea, restless legs syndrome, and narcolepsy.
• Comfort and Safety: Despite the sensors and monitoring equipment, sleep labs aim to create a comfortable environment. Technicians ensure your safety and well-being throughout the night.

Remember, in-lab sleep testing provides valuable insights for diagnosing sleep-related issues. If you suspect any sleep disturbances, consult one of our healthcare professionals to determine whether an in-lab study is necessary for you.
