Provent Sleep Therapy - Starter Kit by 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.

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 is primarily intended for those with Mild and Moderate OSA, who have tried CPAP and are finding it difficult to maintain compliance (i.e. use regularly). In terms of the effectiveness of the treatment, CPAP remains the “gold standard” - but if a patient is unable to use it every night, then Provent is available as an alternative treatment option.

While 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. Because the pressure created through Provent is not strong as CPAP can achieve, it is only suitable for Mild and Moderate Sleep Apnoea. It simply cannot create enough pressure for Severe OSA, for which CPAP remains the only proven treatment option.

Provent is also useful for short-term use while travelling, thanks to its small, simple design. Each night’s set is individually pouched. There is no need for electricity or equipment, and the device is discarded after single-use.
