Patient Selection & Acclimation


Provent Therapy is clinically effective, and FDA cleared, across all levels of severity of obstructive sleep apnea (OSA).1

Recommended Patients for Provent Therapy Include:

  • Patients with mild, moderate or severe OSA who have rejected or are non-compliant with prescribed CPAP
  • Newly diagnosed mild or moderate OSA patients without significant co-morbidities
  • CPAP compliant patients looking for alternatives for travel

Provent Therapy is indicated for the treatment of obstructive sleep apnea (OSA).

See Instructions For Use for contraindications, warnings, precautions and adverse reactions. Based on clinical studies involving similar therapies, Provent Sleep Apnea Therapy is contraindicated for use in patients with the following conditions:

  • 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.

Acclimating to Provent Therapy & Setting Expectations
It may take up to a week or longer for patients to acclimate to breathing with Provent Therapy. The healthcare provider plays an important role in setting acclimation expectations as well as providing important recommendations to facilitate acclimation. These include:

  • Inform the patient that the first few nights using Provent Therapy may be difficult, but that it improves over the ensuing days.
  • The patient will feel pressure when breathing out; explain this is normal and means that Provent Therapy is working.
  • Suggest the patient remove the device during initial nights if he/she has difficulty sleeping with the device.
  • Instruct the patient to breathe through the mouth while awake and falling asleep. The patient will naturally shift to nasal breathing when asleep.
  • The patient may experience anxiety when first wearing Provent Therapy; this is normal and should improve with repeat usage.
  • Some patients may experience dry mouth while wearing the device; advise the patient to keep a glass of water nearby.
  • If the patient has difficulty using Provent Therapy the first few nights, let him/her know it's okay to remove the device and try again the next night; it should become more comfortable over time.
  • Share the How EPAP Works Video to help your patient visualize how treatment works.
