WHAT IS PROVENT?
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.
WHAT IS EPAP?
Provent Therapy utilizes a proprietary MicroValve technology to create “Expiratory Positive Airway Pressure” or EPAP. 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 creates EPAP, increasing and maintaining pressure to help keep the airway open until the start of the next inhalation.
HOW DOES PROVENT THERAPY WORK?
The Provent Therapy device attaches over the nostrils. 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 and helps to keep it open.
HOW IS PROVENT THERAPY DIFFERENT FROM CPAP THERAPY?
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.
CAN I USE PROVENT IF I AM A MOUTH BREATHER?
As with nasal CPAP therapy, Provent Therapy users who may be mouth breathing during sleep may benefit from the use of a chinstrap.
