Nasal Ventilation Cannula System and Methods

Abstract

A nasal cannula ventilation system is described for treating lung disease or for exercise conditioning, incorporating a Venturi system. The ventilation cannula comprises unique positioning features to positively locate a gas delivery nozzle in an optimal location to optimize Venturi performance, patient comfort and fitment to the patient. The cannula is low profile, making it as realistic to wear and use as a standard oxygen cannula, and is simple rending the cost reasonable. The ventilation cannula uses a simple low cost ventilator as a gas delivery control system which is compatible with existing gas sources. The system is used (1) during stationary use to unrest the respiratory muscles to increase tolerance to activity after a treatment session, or (2) to enable activity within a distance from a stationary gas source, (3) during ambulatory use using a portable gas source to enable mobility, and (4) for enhanced fitness conditioning.
