It is important to evaluate how each of these different factors interact. Their brain waves may be affected by movement, which in turn may be affected by respiration. For example, some people may have abnormal brain waves during sleep that prevent them from reaching the expected types of sleep stages. These measurements help us determine the causes of your sleeping problem.
As a result, we need to take several different measurements during the sleep study including heart rate, breathing, sleep level (as measured by the EEG on your scalp), oxygen levels, and movement.
While you are sleeping, your body physiology is different from when you are awake. What is measured during a sleep study and why? Even if you are unaware of any breathing problems, you may still have sleep apnea if you do not sleep well. Some people may have other symptoms such as morning headache, fatigue, weight gain or worsening memory. Not all people with apnea have sleepiness during the day or insomnia at night. It may also lead to increased plaque build-up in your arteries of the heart and brain, and is associated a higher risk of stroke and heart attack. This causes stress on your heart, which can lead to low oxygen levels, hypertension, and heart rhythm problems. The most common type of sleep problem, sleep apnea, is a disorder in which your breathing is irregular at night. The goal of the study is to obtain data that will help the physician determine the next steps in your care.
Your doctor has ordered a sleep study due to a concern that you may have a sleep disorder that is affecting your health. What to Expect at Your Sleep Study Why do I need a sleep study?
