What is the minimum acceptable SaO2 for stroke management?

Explanation:
Maintaining adequate oxygenation is essential in acute stroke because brain tissue depends on sufficient oxygen delivery. When saturation drops, oxygen delivery to the ischemic areas decreases, which can worsen injury and expand the affected brain region. To minimize this risk, protocols aim to avoid hypoxemia by keeping SaO2 at about 95% or higher. If the patient falls below that level, steps to improve oxygenation—such as providing supplemental oxygen or assisting ventilation—are indicated to bring saturation up to the 95% threshold or above. Hence, 95% is the best target to ensure adequate cerebral oxygen delivery in stroke management.
