How many microarousals are normal during a sleep study? i had 314.

Depends: But that sounds like way too many. Without seeing the report comment can't be made. You should make an appointment with your doctor or a sleep doctor as it sounds as if you have a problem, but it depends on the report, kinds of srousals in one slept.

Varies: Micro arousals can be attributed to many causes. I would rely upon my doctor whom ordered the sleep study or the sleep specialist who evaluates the study to provide you with the best info for your questions.
