Toxic effects of high oxygen tension include all of the following, EXCEPT:
The High oxygen tension in inspired air produces cerebral vasoconstriction and reduces cerebral blood flow, thereby protecting the brain from the dangers of oxygen toxicity. Hence in this case, decreased cerebral blood flow is a protective mechanism and not a toxic effect of oxygen.
