The guidelines for oxygen therapy vary depending on the patient's condition and the type of therapy being used. Generally speaking, oxygen therapy is used to treat hypoxemia, which is a condition in which the body is not getting enough oxygen. The goal of oxygen therapy is to increase the amount of oxygen in the blood to improve the patient's overall health and wellbeing. Common guidelines for oxygen therapy include monitoring the patient's oxygen levels and adjusting the oxygen flow rate accordingly. Additionally, the patient should be monitored for any side effects or complications.
