Mouth breathing offers up to 2.5 times more resistance than nose breathing1. This increase in resistance will result in higher negative pressure swings in the airway, possibly causing airway collapse. Breathing through the O2Vent Optima device offers little to no resistance which will reduce negative pressure swings and provide a more stable airway. The design and cross-section of the bi-lateral airway management technology was made to mimic an average patent airway.
