Oxygen Nasal Prong is also known as Nasal Cannula.
It is used to deliver supplemental oxygen or increased airflow to a patient or person in need of respiratory help. This device consists of a light weight latex free 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. The other end of the tube is connected to an oxygen supply such as a portable oxygen generator, or a wall connection in a hospital via a flow meter. The cannula is generally attached to the patient by way of the tube hooking around the patient's ears or by elastic head band. The earliest, and most widely used form of adult nasal cannula carries 15 litres of oxygen per minute.
Cannula with smaller prongs intended for infant or neonatal use can carry less than one litre per minute. Flow rates of up to 60litres of air/oxygen per minute can be delivered through wider bore humidified nasal cannula.
