Abstract
Systems and methods for mixing at least two gases for delivery to the airway of a subject use a gas mixing circuit having a diffusion portion. The diffusion portion may be configured to elongate the shape of the cross-section of the path through the gas mixing circuit in a particular direction and/or orientation. As a result, the gas concentration profile of the gas mixture after the gas mixing circuit is more uniform than the gas concentration profile after the merging of multiple gases.
