METHODS, SYSTEMS AND DEVICES FOR NON-INVASIVE OPEN VENTILATION WITH GAS DELIVERY NOZZLES IN FREE SPACE

摘要

A non-invasive ventilation system may include an interface. The interface may include at least one gas delivery jet nozzle adapted to be positioned in free space and aligned to direct-ly deliver ventilation gas into an entrance of a nose. The at least one gas delivery jet nozzle may be connected to a pressurized gas supply. The ventilation gas may entrain ambient air to elevate lung pressure, elevate lung volume, decrease the work of breathing or increase airway pressure, and wherein the ventilation gas is deliv-ered in synchrony with phases of breathing. A support for the at least one gas delivery jet nozzle may be provided. A breath sensor may be in close proximity to the entrance of the nose. A patient may spontaneous breathe ambient air through the nose without be-ing impeded by the interface.
