Provent Therapy Frequently Asked Questions

Provent Therapy Frequently Asked Questions

1. What is Provent Therapy?

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.

2. What is EPAP?

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.

3. How does Provent Therapy work?

Constant 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.
