Home Sleep Testing is a novel, new way to diagnose Sleep Apnea. It is best used as a screening study for breathing related sleep disorders. We have also found it to be useful in documenting the effectiveness of therapy in those already being treated for Sleep Apnea. Home Sleep Testing is performed in the patient’s home and monitors basic parameters of breathing needed to diagnose Sleep Apnea. If positive, it should be followed by a formal study done in the sleep center, as it does have some limitations. In some cases however, we can proceed right to treatment in the lab. Home Sleep Testing decreases the time patients have to spend away from home and can decrease the number of sleep studies from two to one. It must be interpreted by a board certified sleep specialist and should be scored by a registered sleep technologist.
