Provent Therapy is a simple, non-invasive treatment for obstructive sleep apnea (OSA). The Provent Nasal Device uses a valve design that attaches over the nostrils and is secured in place with hypoallergenic adhesive. The valve opens and closes, redirecting air through small holes to create resistance when breathing out. Because Provent Therapy is a small, single use, disposable device, it's also discreet and very convenient.

Provent Therapy utilizes a proprietary MicroValve technology developed by Theravent, Inc. The device attaches over the nostrils with a hypoallergenic adhesive. During inhalation, the valve opens, allowing the user to breathe in freely. When exhaling, the valve closes and air passing through the nose is directed through two small air channels. This increases the pressure in the airway (called EPAP or expiratory positive airway pressure), maintains pressure and helps to keep the airway open until the start of the next inhalation.

Provent therapy is cleared by the US FDA for the treatment of Obstructive Sleep Apnea.

Provent Therapy may not be appropriate for everyone. If you have been diagnosed with OSA and are considering Provent Therapy, you should speak to your physician to evaluate your individual medical needs.

There is no cure for obstructive sleep apnea. Untreated OSA has a number of potential serious side effects. These include excessive daytime sleepiness, increased risk of high blood pressure, heart attack, stroke, diabetes, depression, increased risk or worsening of heart failure, and increased likelihood of driving or work-related accidents.

Continuous Positive Airway Pressure (CPAP) increases the pressure on both inhalation and exhalation; Provent Therapy increases the pressure on exhalation only. CPAP increases pressure in the airway using forced air, while Provent Therapy uses the patient's own breathing to create pressure during exhalation.

If you are not using your CPAP machine all night, every night then ask your physician about non-CPAP alternatives including Provent Therapy. Only you and your physician can decide what therapy is best for you. If you would like to contact a doctor who is already prescribing Provent Therapy, click here.

Because of its small, simple design, traveling is easy with Provent Therapy. Each night's set is individually pouched. There is no need for electricity or equipment, and the device is discarded after single-use.

Provent Therapy cannot be used together with a CPAP machine, but some users find that it's more convenient to use Provent when traveling and CPAP when at home.
