A study appearing in the November 2011 issue of the Journal of  Clinical Sleep Medicine finds that obstructive sleep apnea (OSA)  patients treated with Provent Sleep Apnea Therapywere not only compliant  with the therapy but also showed a reduction in apnea-hypopnea index  (AHI).

“This study provides further validation that Provent Therapy is an  effective treatment for some OSA patients as it reduces daytime  sleepiness, apnea-hypopnea index (AHI), and snoring associated with this  prevalent condition,” said Meir Kryger, MD, of Gaylord Sleep Medicine  and past president of the American Academy of Sleep Medicine.

“Patients  reported wearing the device almost 90% of the nights, which represents  very high compliance. The current gold standard, continuous positive  airway pressure (CPAP) is very effective but many patients do not use it  adequately. Provent represents an important new treatment option for  many obstructive sleep apnea patients.”

The 13-center, 12-month study was an extension of the 3-month study  that was previously published in the journal SLEEP.  Patients who were compliant with the device and demonstrated adequate  treatment were enrolled for this extension study. These patients showed a  70% reduction in the median AHI after 12 months of treatment with  Provent Therapy. In addition, the study found a very high nightly  compliance rate of 89%. Epworth Sleepiness Scale (a measure of  sleepiness) was reduced five points and snoring was reduced by 74%.

“As we expand our footprint in the United States and international  markets, we believe it is critically important to have solid  peer-reviewed, high quality research like this study to validate the  benefits of using Provent Therapy to treat OSA,” said Peter Wyles,  president and CEO of Ventus Medical. “We commend Dr Kryger and his  colleagues on the results of this important long-term study.” (Source: Sleep Review )
