As far as a sleep study, when is split-night evaluation polysomnogram (PSG) and continuous positive airway pressure (CPAP) titration done?

ANSWER

Split-night PSG with CPAP titration is done when moderate or severe sleep apnea is found or strongly suspected during the first part of the night's study. The second half of the night is used to determine the CPAP pressure needed to offset apnea. Treatment with CPAP (continuous positive airway pressure) puts air into your airways through a specially designed mask.
