1. A respiratory interface for the treatment of breathing problems configured to be in flow communication with at least one of a user's nostrils, the respiratory interface comprising:
at least one body with a gas passageway, wherein the at least one body has a sealing portion that is configured to contact the user's nose, a distal end configured to allow gas to enter the at least one body and a proximal end configured to allow gas to exit the at least one body into the at least one nostril of the user during inhalation, wherein the proximal end is configured to allow gas to enter the at least one body from the at least one nostril of the user and the distal end is configured to allow gas to exit the at least one body during exhalation;
at least one nasal aperture at the proximal end of the at least one body; and
at least one element for adjusting the back pressure generated by the device during use, wherein the respiratory interface is not connected to a gas supply during use for treatment, wherein the respiratory interface is configured to resist flow more during exhalation than during inhalation during use, and wherein adjusting the back pressure generated by the device during use comprises adjusting a resistance to flow from a first value to a second value.
