A Night in the Sleep Lab: What to Expect During Your Sleep Study

If your doctor has recommended an in-lab sleep study, you may have questions about what the procedure entails. In this blog post, we will provide an overview of what to expect during an in-lab sleep study, helping you feel prepared and informed.

  1. What is an In-Lab Sleep Study? An in-lab sleep study, also known as polysomnography (PSG), is a diagnostic test conducted in a specialized sleep laboratory to evaluate and diagnose sleep disorders. It involves monitoring various physiological parameters during sleep, such as brain activity, eye movements, heart rate, breathing patterns, and oxygen levels.  It is much more comprehensive than an at-home sleep test and is able to test for a variety of sleep-related diagnoses and disorders.
  2. Preparing for the Study: The sleep lab staff will provide specific instructions to prepare for the in-lab sleep study. These may include avoiding caffeine or certain medications before the study, adhering to a regular sleep schedule, and arriving at the sleep lab with clean hair and without any styling products.
  3. During the Study:
  • Arriving at the Sleep Lab: You will be asked to arrive at the sleep lab in the evening. A registered sleep technologist will guide you through the process and answer any questions you may have.
  • Electrode Placement: The sleep technologist will attach small sensors called electrodes to specific areas of your scalp, face, chest, and legs using adhesive or tape. These electrodes are painless and non-invasive, and they are used to monitor brain activity, eye movements, muscle activity, heart rhythm, and breathing patterns during sleep.
  • Monitoring Equipment: The electrodes are connected to monitoring equipment, which records your physiological signals throughout the night. These signals provide valuable information for evaluating your sleep patterns and diagnosing sleep disorders.
  • Sleep Environment: The sleep lab is designed to resemble a comfortable bedroom, and efforts are made to create a relaxing and natural sleep environment. You will have a private room equipped with a bed, pillows, and bedding to ensure your comfort during the study.
  • Overnight Monitoring: The sleep technologist will continuously monitor your sleep and the recorded data from an adjacent control room. They will ensure that the equipment is functioning properly and that you are safe throughout the study.
  1. Duration and Aftercare: An in-lab sleep study typically lasts for one night. In some cases, additional multiple-night studies may be required. After the study is complete, the sleep technologist will remove the electrodes. You can resume your normal activities afterward, although you may feel slightly fatigued due to the change in routine.
  2. Discussing Results: Once the sleep study is complete, the recorded data will be analyzed and interpreted by a sleep specialist. They will review the findings and provide a detailed report to your doctor. Your doctor will discuss the results with you, explain any sleep disorders identified, and work with you to develop a treatment plan if necessary.

Remember, an in-lab sleep study is a painless and safe procedure that provides valuable insights into your sleep patterns and helps diagnose sleep disorders. It plays a crucial role in evaluating your sleep quality and guiding treatment decisions.

Your sleep specialist and the sleep lab staff will guide you through the in-lab sleep study process, ensuring your comfort and well-being throughout the procedure.

If you have any specific concerns or questions about the in-lab sleep study, don’t hesitate to discuss them with your sleep specialist. They can address any doubts and provide personalized information based on your unique situation.
