What indicates the need for immediate oxygen therapy?

The need for immediate oxygen therapy is indicated primarily by marked hypoxemia or distress. When a patient is experiencing hypoxemia, it means their blood oxygen levels are critically low, which can lead to severe complications. Symptoms of hypoxemia may include confusion, shortness of breath, rapid heart rate, or cyanosis. In such cases, prompt oxygen delivery is essential to restore adequate oxygen levels in the bloodstream and prevent further deterioration of the patient's condition.

While stable vital signs, consistent normal saturation levels, and patient comfort level are important indicators of a patient's overall health, they do not signal an immediate need for oxygen therapy. Stable vital signs may indicate that a patient's condition is under control, and normal saturation levels suggest that oxygenation is adequate. Patient comfort is certainly a consideration in care, but it does not override the critical need to address respiratory distress or significant hypoxia. Therefore, marked hypoxemia or distress is the clear and urgent call for administering oxygen therapy.
