What is EPAP?
EPAP stands for Expiratory Positive Airway Pressure. EPAP devices have been shown in clinical studies to be safe and effective for treating snoring and mild to moderate sleep apnea.
What is Optipillows EPAP Mask?
The Optipillows EPAP Mask is an EPAP device integrated onto a nasal pillow mask. It looks like a nasal pillow CPAP mask but does not require a CPAP machine. Optipillows EPAP Mask is a nasal mask that generates positive pressure during exhalation.
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 side opening, creating back pressure in the nose and mouth, preventing upper airway collapse. The size of the side opening can be adjusted to change the pressure for more comfort. Start using the mask with the side opening wide open, and close it only after you feel comfortable and begin to fall asleep as usual.
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.
Can Optipillows replace my CPAP machine?
Optipillows EPAP mask is intended for use to treat snoring. For those with severe obstructive sleep apnea, it will not replace your CPAP. However, during travel, some CPAP users don’t like to carry their CPAP with them. In such cases, one can use the Optipillows EPAP mask as another option.
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.
The EPAP mask works for someone with mild sleep disordered breathing such as snoring. It does not work for those with central sleep apnea, needing to use a full face mask, or those who need a BIPAP machine. While using the EPAP mask , the mouth must remain closed for the mask to work.
