Sleep apnoea is a common sleep disorder that causes excessive sleepiness and increased motor vehicle accident risk. Not all patients are affected equally by sleep apnoea. Current clinical tests are poor at determining who presents a crash risk on the road. This study will assess a range of sleepiness measures in sleep apnoea patients. These measures include:
- self-reported trait sleepiness
- self-reported crash risk
- sleep apnoea severity determined by overnight sleep study
- objective sleepiness determined by the maintenance of wakefulness test
- objective sleepiness determined by psychomotor vigilance test
- objective sleepiness as determined by brain waves and eye blink measures
Each of these measures will be compared to determine which of these measures best predict and relate to sleepiness and adverse driving events during regular driving recorded during a 10 day period.
