The [b]nasal cannula[/b] is a device used to deliver supplemental oxygen or increased airflow to a patient or person in need of respiratory help. It consists of a lightweight elastic tube which on one end splits into two prongs which are placed in the nostrils and from which a mixture of air and oxygen flows.
