Do many hospital patients require a nasal cannula? When is it administered?

While just one component of a system for delivering oxygen to patients at risk of hypoxia, or a shortage of oxygen reaching cells, nasal cannulas are the part that actually sits at the base of the nostrils to enable oxygen from a tank to which it is connected by a clear, plastic tube or hose, to enter the breathing passages. Nasal cannulas are used for people, usually elderly, with chronic breathing problems, such as occurs from diseases like emphysema. The amount of oxygen delivered from the tank through the nasal cannula is calibrated according to the specific needs of each individual patient. Nasal cannulas are generally used for patients with breathing difficulties, but for whom a sudden intake of large quantities of oxygen are not required. The latter category is generally only administered in a hospital or other medical facility for patients experiencing trauma. Nasal cannulas, in contrast, are more a function of enabling people with diminished lung capacity to continue to lead relatively normal lives. When attached to a mobile oxygen tank, use of nasal cannulas enables users to remain mobile, albeit with the caveat of having to transport the oxygen tank wherever they go.
