Oxygen Therapy for Acute Stroke: Indications and Considerations

In acute stroke, oxygen therapy is indicated for patients with hypoxemia (low blood oxygen), which can arise from:

• Reduced respiratory drive (brainstem involvement)
• Aspiration from dysphagia causing pneumonia
• Neurogenic pulmonary edema
• Right heart failure

Oxygen is administered via nasal cannula, face mask, or other devices based on patient needs. However, therapy must be titrated to maintain target saturation and avoid hyperoxia (excess oxygen), which can cause absorption atelectasis and oxidative stress. Regular monitoring of oxygen saturation and clinical assessment is essential for optimal outcomes.
