A nasal cannula assembly is disclosed having a face mount part, in use resting against a user's face, which includes at least one nasal prong capable of being fitted into a person's nares. The cannula assembly also includes a manifold part, in fluid communication with the face mount part, having a single horizontal side gases entry. In particular, this cannula assembly is for supplying heated, humidified gases to a patient suffering from COPD. A tie or lanyard is disclosed for use with a breathing assistance apparatus such as a nasal cannula, face or nasal mask or tracheostomy connector. The tie or lanyard transfers the weight of the conduits supplying gases to the breathing assistance apparatus from the breathing assistance apparatus and distributes it onto the neck of the patient.
