Which of the following is a primary purpose of oxygen therapy?

Oxygen therapy is meant to improve the amount of oxygen getting into the blood and tissues. When blood oxygen is low, adding supplemental oxygen increases the oxygen that reaches the lungs and diffuses into the bloodstream, raising oxygen saturation and helping prevent tissue hypoxia. This is the primary goal because keeping tissues well-oxygenated supports organ function and reduces the harm from low oxygen levels. It isn’t used to dry out mucosa, eradicate infections, or aid digestion, which is why those options aren’t appropriate.
