In stroke management, which statement accurately describes oxygen administration?

The main idea is to balance oxygen delivery to the brain: provide enough to prevent hypoxia, but avoid giving so much that hyperoxia could cause harm. In stroke, tissue that is already at risk (the ischemic penumbra) needs adequate oxygen, but excessive oxygen can lead to vasoconstriction and oxidative stress, potentially worsening injury. So you give enough supplemental oxygen to correct low oxygen levels and then adjust to avoid hyperoxia. Target oxygen saturation is kept in a normal range (often about 94–98%), not automatically 100%. If a patient isn’t hypoxic, you wouldn’t push to 100% oxygen. Cyanosis alone isn’t the sole trigger for oxygen in stroke; monitor SpO2 and administer oxygen to maintain appropriate levels.
