Oxygen delivery is a research area focused on studying the mechanisms and processes involved in the transport of oxygen from the lungs to the tissues in the body. This includes exploring the complex interactions between the cardiovascular and respiratory systems, as well as the role of hemoglobin and red blood cells in carrying oxygen to the cells. Researchers in this area investigate various factors that can affect oxygen delivery, such as exercise, altitude, medical conditions like anemia or respiratory disorders, and the use of supplemental oxygen therapy. Understanding oxygen delivery is critical for optimizing athletic performance, managing medical conditions, and improving overall health and well-being.
