Split Night Studies
The gold standard for diagnosing many types of sleep disorders is the diagnostic polysomnogram. Once obstructive sleep apnea is diagnosed, a second night of polysomnography with the addition of CPAP is often performed to treat the obstructive breathing. Ideally, a full night of diagnostic data is obtained and analyzed prior to the initiation of treatment in order to allow the interpreting physician to examine the data in detail before making therapeutic recommendations, and in order to allow you adequate sleep time in an unusual environment. In addition, a full night of CPAP therapy is preferred in order to allow adequate time for the technologist to perform an optimal titration, and to allow you adequate time to adjust to the CPAP and cycle through all stages of sleep.
