Flow costs up to 6 lt could be given but this will likely often trigger nasal dryness and even can be not comfortable for patients (British Thoracic Society, 2008).


The advantages of nasal cannulas intended for patients who have got chronic stable respiratory problems is it is possible to eat, take in and talk with all the them; they in addition slow up the risk associated with carbon dioxide rebreathing.
