OSA & Driving

Obstructive sleep apnoea (OSA) and daytime driver sleepiness was the topic of my Ph.D (2011). In a series of driving simulator investigations this work demonstrated that OSA patients who have been using continuous positive airway pressure (CPAP) treatment for at least 1 year show no difference in performance at driving in a simulator than healthy controls. However, OSA patients were more vulnerable to sleep loss, and without their CPAP treatment driving performance was significantly impaired compared to drivers of a similar age without OSA.
