Oxygen Nasal Prong is also knwon as Nasal Cannula.
It is used to deliver supplemental oxygen or increasedairflow to a patient or person in need of respiratory help. This deviceconsists of a light weight latex free tube which on one end splits into twoprongs which are placed in the nostrils and from which a mixture of air andoxygen flows. The other end of the tube is connected to an oxygen supply suchas a portable oxygen generator, or a wall connection in a hospital via aflowmeter. The cannula is generally attached to the patient by way of the tubehooking around the patient's ears or by elastic head band. The earliest, andmost widely used form of adult nasal cannula carries 1â5 litres of oxygen perminute.
Cannula with smaller prongs intended for infant orneonatal 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 humidifiednasal cannula.
