What patient condition may require supplemental oxygen for support?

Supplemental oxygen is often necessary for patients with acute respiratory distress syndrome (ARDS) because this condition involves severe inflammation and fluid accumulation in the lungs, which impairs gas exchange. Patients with ARDS struggle to get enough oxygen into their bloodstream due to the compromised state of their lungs, leading to hypoxemia (low oxygen levels in the blood). Providing supplemental oxygen helps to increase the amount of available oxygen, improving tissue oxygenation and supporting the patient's overall respiratory function.

In contrast, conditions like chronic headaches, fatigue, and orthopedic injuries do not typically result in impaired gas exchange to the same extent as ARDS does. While they may cause discomfort or other symptoms, they generally do not require the same level of oxygen support, making it essential to recognize the specific clinical needs associated with respiratory conditions when considering oxygen therapy.
