Final answer:
A nasal cannula is a medical device used to deliver supplemental oxygen to patients. It consists of prongs that are placed into the nostrils and connected to an oxygen source. The nasal cannula allows patients to breathe more easily and increase their oxygen levels.
Step-by-step explanation:
A nasal cannula is a medical device used for delivering supplemental oxygen to patients who have difficulty breathing or low oxygen levels. It consists of two small prongs that are placed into the nostrils, connected to a tube that delivers oxygen from an oxygen source. The function of a nasal cannula is to deliver a controlled flow of oxygen directly to the patient's respiratory system, allowing them to breathe more easily and increase their oxygen levels.
One advantage of using a nasal cannula is that it is comfortable and easy to use. The prongs are soft and flexible, and they can be adjusted to fit comfortably inside the patient's nostrils. Another advantage is that it allows the patient to eat, drink, and speak while still receiving oxygen therapy. However, it is important to properly clean and maintain the nasal cannula to prevent infections or complications.
