After having a polysomnogram you may be diagnosed with obstructive sleep apnea and be asked to undergo a split-night study. This is a full night study consisting of a diagnostic polysomnogram followed by a continuous positive airway pressure (CPAP) interventional therapy.
A technologist performs continuous positive airway pressure (CPAP) interventional therapy through all cycles of sleep while you adjust to the CPAP theraphy. Diagnostic data is recorded and then analyzed by a physician to make therapeutic recommendations to treat obstructive breathing.
