With the oral interface in position and iNAP turned on, bring your tongue to the bottom of your mouth. This sensation pulls the tongue toward the upper palate and the soft palate forward. As you begin to feel the negative pressure (gentle suction) in your throat, slowly allow your tongue to rise and position itself under the straw. It should take 10-15 seconds to achieve negative pressure in your oral cavity. 

In your first month of use, the seal time average (time spent using the device and acheiving negative pressure) is 60% – 70%. While continuing to acclimate during months 2-3, this percentage is likely to improve to 85%-99%. We suggest a goal of at least 80%.

To Improve Sealing

Swallowing during the night can help maintain a seal. To help improve your seal, you can also try:

• Making a humming sound
• Bringing your tongue to the upper palate and forwarded position, behind your top front teeth
• As if using a straw, draw in the stamen, the part of the interface that extends farthest in your mouth

Note: Individuals may experience different results based on their OSA severity and oral anatomy.
