What is one method of administering oxygen therapy?

Administering oxygen therapy through a nasal cannula is a common and effective method used to deliver supplemental oxygen to patients. A nasal cannula consists of a flexible tube with two prongs that fit into the nostrils, allowing for a comfortable flow of oxygen while enabling patients to speak and eat more easily than some other delivery methods.

This method is particularly beneficial in clinical settings where patients require low to moderate concentrations of oxygen, providing a continuous supply without the need for more invasive procedures. It is also well-tolerated by most individuals and can be adjusted according to the flow rate required for the patient’s condition. In contrast, other methods listed—such as administering medication in pill form, topical ointments, or syringe injections—are not used for oxygen therapy because they do not facilitate the direct delivery of oxygen into the respiratory system in the way that a nasal cannula does.
