Works like a nasal pillow CPAP mask but without tubing or a machine
What is Optipillows EPAP Mask?
OptiPillowsTM  is an EPAP nasal mask. It is not a CPAP mask. With CPAP, one needs a CPAP machine, a power supply, and one remains tethered to the CPAP tubing. With CPAP, the pressure in the airways remains positive throughtout the breathing cycle. With EPAP, the pressure is positive only during expiration, without using a CPAP machine or tubing. With the EPAP mask, one is free to move during sleep.  There is evidence that the EPAP devices work well for all severities of snoring and sleep apnea..
Snoring and obstructive sleep apnea
Snoring and airway obstruction are due to events occurring in the upper airway.  At end expiration, the upper airway is most susceptible to collapse, because the pressure is low, upper airway is narrowest, lung volume is smallest, and muscles are most relaxed. Consequently, when inhalation begins, and a small negative is created, it causes potential upper airway collapse. With the EPAP mask, collapse of the upper airways is prevented by maintaining a positive expiratory pressure during expiration. The EPAP mask works using expiratory resistance technology that have been shown in clinical trials to be effective in treating snoring and all severities of obstructive sleep apnea. The EPAP mask is easy to use. If you tried other expiratory resistance devices previously, you will like OptiPillows EPAP Mask. The EPAP mask is reusable, and can be used perhaps up to 1 year.
How much pressure is generated?

  The pressure during expiration can be adjusted by rotating the sleeve to close or open the side resistance. 

                        With side resistance fully open, it generates 1 to 3 cmH2O of pressure.
                        With side resistance 50% closed, it generates 3 to 7 cmH2O of pressure.​
                        With side resistance 75% closed, it generates 8 to 14 cmH2O of pressure.​​
Caution: It is very important to become able to sleep comfortably with the EPAP mask with the lowest resistance, before increasing the expiratory pressure. ​
Frequently Asked Questions:

1. What is EPAP? 
     EPAP stands for Expiratory Positive Airway Pressure. The EPAP mask is a nasal mask that generates positive pressure during

     expiration. Scientist have known for many years that sleep apnea and snoring can be alleviated by applying positive pressure
     during  expiration. The EPAP mask my keep you awake the first time you use it. Do not give up after one try. It is not magic, like
     other devices, it may take a few nights to get used to it. If you cannot fall asleep, take it off. It will become easier and easier after
     each night.

2. What is Optipillows EPAP Mask? 
     The EPAP Mask is an EPAP device integrated onto a nasal pillow mask. It is used like a CPAP mask but does not require a CPAP

      machine. EPAP devices such as Theravent and Provent were introduced a few year ago, and have been shown in clinical studies
      to be safe and effective in treating snoring and obstructive sleep apnea. 

3. How does OptiPillows work?     
     OptiPillows EPAP Mask allows you to inhale easily with minimal resistance, but during exhalation, the air is directed through a

     narrow opening, creating back pressure in the nose and mouth, preventing snoring and sleep apnea. The size of the side opening
     can be adjusted to change the pressure during exhalation. 

4. Is Optipillows right for me? 
     There is evidence that EPAP devices are as effective as CPAP in some patients with snoring and mild obstructive sleep apnea.  

5. How is EPAP different from CPAP?  
      CPAP, as the name indicates, provides continuous positive airway pressure throughout the breathing cycle. In contrast,

      OptiPillows EPAP mask provides positive pressure only during the expiratory phase of the breathing cycle.

6. How is Optipillows different from Provent? 
      Both use expiratory resistance technology, but Optipillows EPAP mask is reusable, easy to wear.
Furthermore, Optipillows EPAP
      mask has an adjustable expiratory resistance .

7. Can Optipillows replace my CPAP machine?
       For people with snoring or with mild to moderate sleep apnea, it is possible that OptiPillows will work as well as a CPAP

      machine.  It is recommended that people with severe obstructive sleep apnea should continue to use their CPAP and perhaps
      resort to using the EPAP mask only during travels or camping. 

8. Do I need a perscription?  
      For now you do not need a prescription to purchase Optipillows EPAP mask.

9. Can I use Optipillows during travel?  
       Optipillows EPAP mask is ideal for use during travel. You can store it in your pocket to use anytime, such as during flight or

        camping. No power supply  is needed. 

10. I have severe OSA, is it safe to use Optipillows? 
         Someone with severe sleep apnea may benefit only partially. Therefore, use it only during emergency such as during travel or

        when the power is out, but don’t replace your CPAP with an EPAP device.

11. I have central sleep apnea, can I use Optipillows? 
        Patients with central sleep apnea should rely on their CPAP machines, and should adhere to their prescribed therapy. 

12. I use a full face mask, can I use Optipillows?
        OptiPillows EPAP mask uses a nasal pillow type mask and may not be suitable for someone who needs a full face mask. 

13. How often should I replace my Optipillows? 
        Perhaps once a year, just like you would do with a CPAP mask. 

14. I open my mouth sometime, is that a problem? 
        Opening the mouth occasionally to sigh or cough is not a problem while using EPAP devices. After a breath or two, the pressure

        will rise again. With CPAP, opening the mouth, causes dryness because of the high volume of air flowing through the mouth.
        Dryness of the nose or throat is not a problem with the EPAP mask.
