BELMONT, Calif., Feb. 14, 2011 /PRNewswire/ -- A peer reviewed study in the February issue of Sleep Medicine concluded that Provent® Sleep Apnea Therapy, a non-invasive, disposable nasal device, significantly improved obstructive sleep apnea (OSA) - as measured by the number of breathing disruptions during sleep - in more than half of patients, leading them to feel more alert during the day. The study was conducted in patients who had either refused or were non-compliant with CPAP (Continuous Positive Airway Pressure) therapy.
The study, conducted at St. Luke's Hospital Sleep Medicine and Research Center in Chesterfield, Missouri, near St. Louis, included 59 patients and is titled "A convenient expiratory positive airway pressure nasal device for the treatment of sleep apnea in patients non-adherent with continuous positive airway pressure."
Provent Therapy was accepted by eighty percent of patients who were not using CPAP regularly or were untreated. CPAP therapy requires wearing a mask that is connected to an air blower while sleeping. The study also found that Provent Therapy improved blood oxygen saturation and resulted in less daytime sleepiness as measured by the Epworth Sleepiness Scale. Treated patients reported feeling less sleepy during the day and having better quality of life. Patients that completed the study reported using Provent Therapy more than ninety percent of total sleep hours, representing very high treatment adherence.
"CPAP therapy is the standard of care for the treatment of obstructive sleep apnea, but a large percentage of patients are not able to tolerate it and express dissatisfaction with their treatment options.
