Continuous Negative External Pressure (cNEP)

Continuous Negative External Pressure (cNEP) is a new technology that is used for the treatment of obstructive sleep apnea (OSA) and sleep disordered breathing. It works by applying a negative pressure (suction) to the neck area in order to widen the mid-upper airway during sleep.

cNEP vs. CPAP

cNEP offers a potential to be an alternative to CPAP (continuous positive airway pressure).  CPAP is the most popular treatment for obstructive sleep apnea. While CPAP works by introducing constant positive pressure inside of the airway,  cNEP applies negative pressure outside of the airway.

Many OSA patients complain of dry mouth and nose while using CPAP. cNEP offers the possibility of bypassing the mouth/nose in order to affect the airway.

cNEP Continuous Negative External Pressure vs. Iron Lung

Continuous Negative External Pressure works in familiar manner as the ‘Iron Lung’ that was popularized during the polio epidemic during the 1930’s. While the iron lung is a negative pressure ventilator that varies pressure outside of the chest walls in order to expand and contract the lungs, cNEP applies a constant negative external pressure to the neck area in order to expand the airway that underlies the contact area.

Sommetrics , Inc is a California corporation that has developed a new technology called the “aer+ ™” that uses cNEP. It has been FDA cleared and will be distributed in Canada in 2018.
