Harvard researchers examining new sleep apnea screening tool

www.chinatrucks.com: A simple test that measures attention, alertness and reaction time could one day be administered to drivers when they renew their licence to determine if they are likely to suffer from obstructive sleep apnea (OSA), a Harvard study has suggested.

A new study published in the Journal of Occupational and Environmental Medicine and conducted by researchers from Harvard Medical School and Harvard School of Public Health, explored the usefulness of a psychomotor vigilance test (PVT) as a way to screen drivers for sleep apnea.

The PVT is a 10-minute test that can be conducted at a licensing agency or at a driver's home terminal. It's conducted using portable handheld computers and the results can be quickly read and interpreted, the researchers found.
