Embodiment Construction

[0070] figure 1 A prior art conventional oxygen delivery cannula 101 for administering oxygen therapy is shown. The extension 105 on the cannula 101 is configured to enter the nostril 103 . The proximal end (not shown) of the cannula 101 is connected to an oxygen delivery device that delivers either a continuous flow of oxygen at 1-6 LPM or a bolus of oxygen to the user's nose upon detection of an inspiratory effort. figure 1 The system does not mechanically support the patient's work of breathing, but is not believed to be effective in preventing moderate to severe forms of OSA. figure 1 The cannula is also used in another oxygen delivery therapy known as High Flow Oxygen Therapy (HFOT), in which humidified oxygen greater than 15 LPM is delivered to the user's nose at a continuous flow rate. Due to the high flow required for HFOT, the system is non-portable and the oxygen must be humidified.

Abstract

A system for providing ventilatory support includes a nasal interface designed to communicate with a patient's nose while allowing the patient to breathe ambient air directly without passing through the nasal interface. The nozzle may be connected to the nasal interface at a distance from the nose. The nozzle can be connected to a gas delivery circuit and a gas delivery source. The nozzle may be capable of delivering gas into the nasal passages by creating a region of negative pressure near the nozzle and a region of positive pressure near the entrance to the nose. A combination of gas from the gas delivery source and air entrained by the gas exiting the nozzle can provide ventilatory support.
