Patient Selection

Patient selection and acclimation

Reccomended patients for Provent Nasal EPAP include:

  • Patients (mild, moderate or severe) who have rejected or are non-compliant with prescribed CPAP
  • Newly diagnosed mild/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)


Provent Therapy should not be used if patient has any of the following conditions*:

  • Severe breathing disorder (including respiratory muscle weakness, bullous lung disease, bypassed upper airway, pneumothorax, pneumomediastinum, etc)
  • Severe heart disease (including heart failure)
  • Pathologically low blood pressure

*See Instructions For Use for contraindications, warnings, precautions and adverse reactions.

Acclimating to Provent Therapy

The Importance of Acclimation

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:

  • Informing the patient that the first few nights using Provent Therapy may be difficult, but that it improves over the ensuing days
  • Suggesting the patient remove the device during initial nights if he/she has difficulty sleeping with the device
  • Instructing the patient to breathe through the mouth while awake and falling asleep
  • Letting the patient know it may take up a week or more to acclimate to the device

Educate your patient and set expectations

  • The patient will feel pressure when breathing out; explain this is normal and means that Provent Therapy is working
  • Breathe out through the mouth while awake. 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
  • Give it a few days. If the patient has difficulty using Provent Therapy the first few nights, it’s okay to remove the device and try again the next night; it should become more comfortable
  • Share the Provent Therapy mechanism of action animation to help visualize how treatment works
