What are sleep apnea test scores?

Sleep apnea test scores reflect brain activity, breathing, heart rate, oxygen levels, and arm and leg movements recorded during a sleep study, according to Mayo Clinic. Sleep evaluations are usually performed during an overnight stay in a specialized center, although home testing is also possible in some cases.

Sleep studies demonstrate whether a patient experiences drops in oxygen during sleep, which can pose a significant health concern and interfere with restful sleep. If the results of a sleep study are abnormal, patients may require follow-up with specialists such as cardiologists or otolaryngologists for further assessment and treatment of the underlying cause of sleep apnea, reports Mayo Clinic.
