Can i breathe pure oxygen gas?
Breathing pure oxygen is potentially toxic. At reduced pressures, pure oxygen can be inhaled for days, or weeks. It is used to treat individuals suffering from stroke, heart attack, etc. and can be comfortably used for up to 24 hours. The body can be overwhelmed by oxygen during long periods or higher pressures, free radicals in the oxygen cause damage through oxidative stress which can result in tissue damage and death.
