Oxygen nasal cannula - adult
An oxygen nasal cannula is a medical device used to deliver supplemental oxygen to a person who is breathing insufficiently on their own. It is a flexible plastic tube with two prongs that are placed in the nostrils and held in place by a band around the head. The other end of the tube is connected to an oxygen source, such as an oxygen tank or a wall outlet. The oxygen nasal cannula is commonly used in a variety of medical settings, including hospitals, clinics, and homes, to provide additional oxygen to patients with breathing difficulties, such as those with chronic obstructive pulmonary disease (COPD), asthma, or heart failure. The cannula allows for the delivery of oxygen in low to medium concentrations, and it is a noninvasive and convenient alternative to other oxygen delivery methods, such as face masks or intubation.
