Many nurses will care for a patient who requires oxygen therapy, either to treat an acute respiratory condition, such as a lung infection, or a chronic condition, such as chronic obstructive pulmonary disease. This article discusses the physiology of gaseous exchange and provides an overview of some of the main respiratory conditions that may result in the need for oxygen therapy. The author also describes the oxygen delivery devices commonly used in clinical practice, such as simple face masks and nasal cannulas, to assist nurses in selecting the most appropriate device.
