  • Figure 1. Hypnogram of diagnostic polysomnography (A) and continuous positive airway pressure (CPAP) titration (B). Note the profound oxygen desaturation with sleep-disordered breathing regardless of sleep stage and sleep position. Sleep architecture was highly fragmented. REM proportion was relatively preserved, but slow wave sleep was absent. Optimal CPAP terminated sleep-disordered breathing and reduced arousals. Note the remarkable REM rebound (as designated by R in the y axis) with the arrows pointing to these areas of interest. REM; rapid eye movement.
