A nocturnal polysomnogram may cause endless anxiety due to the requirement to spend a night at the sleep lab/center. You will have numerous questions surrounding the requirements and the nature of the test.
Key takeaways:
· Sleep technologists are all prepared for any inquiries from patients to ensure that it is a relaxing and comfortable experience for all irrespective of healthcare needs.
· Ensure that you go about your day as usual and that lab is aware of any special needs that you may have.
· Carry with you pre-test paperwork, current medication list, sleepwear and basic toiletries.
· Avoid smoking, caffeine after lunch, napping in the afternoon, and avoid alcohol to not interfere with the sleep study.
Keep in mind that the sleep medicine technologists at most sleep centers are prepared for all of these inquiries; they are also trained to provide you with a safe, relaxing, and comfortable experience that's based on your specific healthcare needs.
