Abstract
A non-rebreathing facemask removably securable onto a connector which is attachable directly to an aerosol medication system, illustrated for example as an aerosol cloud enchancer for use in respiratory therapy, or an oxygen delivery system. The connector to which the facemask is secured functions in cooperation with the facemask to provide a valving system for discharging a patient's expiratory air outside of the medication or oxygen delivery system, while permitting the patient to smoothly inhale inspiratory air.
