Abstract
Nasal cannulas for providing respiratory therapy to patients can have a body, two prongs extending from the body, and a gases inlet on one side of the body. There can be a throttle or internal localized reduction in the cross-sectional area of a cavity defined by the internal walls of the cannula body in between the prongs. In at least some arrangements, the throttle can partially or substantially fully equalize flow between the prongs of the cannula.
