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.
How does Provent Therapy treat Obstructive Sleep Apnea (OSA)?
Provent Therapy adhesive devices attach over the nostrils. During inhalation, the patented Microvalve 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.
Can Provent be used if I breathe orally?
For Provent to work effectively, the patient must breathe through their nose. Should this not be the case, then the use of a chin strap may be sufficient for prevent oral breathing. However, if nasal breathing is prohibited, for example due to a deviated septum, then Provent would not be suitable.
How long does it take to adapt to Provent?
Much like CPAP, the different sensation of pressure created by Provent can take a few nights to get used to. The Starter Kit includes some devices with reduced resistance, allowing you to adjust more easily before moving onto the standard devices with the full level of resistance.
Will Provent Therapy work for me?
The success rates of Provent are high, with recent clinical studies finding that 81% of OSA patients were successfully treated. Discussions with your consultant will help determine if Provent is right for you. Due to the disposable nature of Provent devices, the upfront cost to start Provent is significantly less than most treatment options. For example, a Provent Starter Kit costs around 15% of a CPAP kit.
Is Provent Therapy safe?
Yes, In recent clinical studies, no device-related adverse events were reported. However, there are some health conditions which would make Provent unsafe; these include severe heart disease (including heart failure), pathologically low blood pressure, and severe breathing disorders. . Always discuss the suitability of Provent with your sleep physician prior to beginning treatment.
Does Provent Therapy stop snoring?
Clinical studies have shown that 83% of patients experienced a snoring reduction with Provent Therapy1. Among OSA patients that snore, Provent Therapy virtually eliminated snoring in 58% of patients.
How is Provent Therapy different from CPAP therapy?
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.
Can Provent Therapy replace my CPAP machine?
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.
Can I travel with Provent Therapy?

What can I expect from my initial experience with Provent Therapy?
After you apply the Provent Device, you should notice the resistance created as you try to exhale. Generally, users get used to this feeling after wearing for several nights.
- Put the devices on just before going to sleep. Breathe out through your mouth. After falling asleep, most people will automatically breathe through their nose.
- Getting used to wearing a device that affects your breathing may take time (one night to a week or longer). Remove the device if you wake up during the night and feel uncomfortable. This may happen for several nights until you become used to wearing the device.
Notes and Tips
- Provent is intended for use by people who can breathe through their nose. Because of the way it functions, people who breathe through their mouth will not receive the benefits of the airway pressure generated by channeling the exhaled air though the valve. If your mouth drops open during sleep consider using a Chinstrap. If you use decongestants continue to use them to maintain free airflow though the nose.
- When awake and wearing Provent, you are encouraged to breathe out through your mouth. You will begin to breathe through the device once you are asleep.
- If you are feeling uncomfortable during the night when using Provent, just take the Provent off and try again the next night.
- It is normal for the Provent adhesive ovals to overlap between the nostrils.
- Excessive nasal hair should be trimmed prior to using Provent to ensure adequate airflow. A mustache may prevent adequate seal around the nare and may require additional trimming.
- Oil/Moisturizer on the surface may prevent the adhesive from sticking. Wipe around the nose with a clean tissue or cloth and allow to dry before applying Provent.
- Provent is not intended to be used simultaneously with a CPAP. Provent may be used on some nights and CPAP therapy used other nights. Do not use CPAP and Provent at the same time. Use Sleep Apnea therapy on a nightly basis to maintain the benefits of the treatment of Sleep Apnea.
- Some people who use Provent when traveling and CPAP when at home find the adjustment between the two natural. Other users find the adjustment period longer.
- If irritation in or around the nostrils occurs discontinue the use of Provent.
- Provent is not cleared for use in children. Provent is intended for use in adults over the age of 18.
- Clinical studies results for Provent show that 83% of people studied showed a reduction in snoring, and further, that in persons with OSA who snore, 58% found that Provent virtually eliminated snoring. It is recommended that you discuss Provent with your physician to see if it is an option for you.
- Patients should not use any single Provent Nasal Device for longer than one sleep cycle (e.g., overnight). The device is intended for single use only and should be disposed of after use. Reuse of the Provent Nasal Device will weaken the adhesive, resulting in an inadequate seal and reduced effectiveness of the device.
Provent is NOT recommended in the presence of any of the following conditions:
- Central Sleep Apnea (CSA) or a patient requiring the use of a BiPAP ST
- Severe breathing disorders including hypercapnic respiratory failure, respiratory muscle weakness, bullous lung disease (as seen in some types of emphysema), bypassed upper airway, pneumothorax, pneumomediastinum, etc.
- Severe heart disease, including heart failure
- Pathologically low blood pressure
- An acute upper respiratory including nasal, sinus or middle ear inflammation or infection or perforation of the ear drum
- Deviated septum
- Those who require the use of supplemental oxygen
- Pregnant women
- Patients have any sores, abrasions, or skin or mucosal irritation on or around the nose.
