The Besmed Oxygen nasal Cannula are designed for comfort for those who need longer term supply of oxygen with curved and non-flared nasal prongs. This nasal cannula device consists of a lightweight tube which on one end splits into two prongs which are placed in the nostrils and from which oxygen flows. There are a number of conditions in which a person might lose the ability to breathe normally and need a comfortable nasal cannula to obtain supplementary oxygen such as Asthma, COPD, and chronic bronchitis, Emphysema, Cystic fibrosis, Pneumonia, Lung cancer or Pulmonary embolism.
