                          Obstructive Sleep Apnea 

SEATTLE, June 9, 2009 (GLOBE NEWSWIRE) -- Ventus Medical, a privately-held medical device company focused on improving the lives of patients with sleep-disordered breathing, today announced that clinical data from three poster presentations presented at the SLEEP 2009 23rd Annual Meeting of the Associated Professional Sleep Societies further confirm PROVENT(r) Sleep Apnea Therapy's clinical utility in treating mild, moderate and severe obstructive sleep apnea (OSA). SLEEP 2009 is being held June 8-11 in Seattle, WA.

OSA occurs when the upper airway (near the back of the mouth) collapses during sleep, obstructing the airway and preventing air from entering the lungs. Pauses in breathing result and are associated with a decrease in oxygenation of the blood.

The reported data also suggest that positive end-expiratory pressure is the mechanism of action by which PROVENT Therapy helps patients with sleep-disordered breathing.(1)
