Abstract

A non-invasive ventilation system may include at least one outer tube with a proximal lateral end of the outer tube adapted to extend to a side of a nose. The at least one outer tube may also include a throat section. At least one coupler may be located at a distal section of the outer tube for impinging at least one nostril and positioning the at least one outer tube relative to the at least one nostril. At least one jet nozzle may be positioned within the outer tube at the proximal lateral end and in fluid communication with a pressurized gas supply. At least one opening in the distal section may be adapted to be in fluid communication with the nostril. At least one aperture in the at least one outer tube may be in fluid communication with ambient air. The at least one aperture may be in proximity to the at least one jet nozzle.
