Nasal Cannulae or Nasal Catheters are used for their simplicity and patient convenience. There is entrainment of air through the nostrils. The Fi02 achieved is proportional to a) the flow rate of oxygen (1-6 l/min), b) the patients tidal volume, inspiratory flow rate and c) the volume of the nasal pharynx. Mouth breathing causes inspiratory air flow which produces a venturi effect in the posterior pharynx entraining oxygen from the nose

Nasal Cannula & Nasal Catheters
At an oxygen flow rate of 2 l/min the oxygen concentration in the hypopharynx of a resting person is 25-30%. Nasal Cannula prevents re-breathing and are comfortable for long periods.
There is increased patient compliance with nasal cannulae as patients are able to speak, eat or drink. Local irritation and dermatitis may occur with high flow rates. Use of humidified oxygen is recommended to reduce dryness of the mucosal wall in the nasal cavities, particularly when using flows of greater than 4 l/min.
