The delivery of external oxygen (O2) depends on the condition. To prevent shock, O2 is often set high, such as 8 L /min. (liters per min). But, in someone with emphysema, for example, anything higher than 2 L/min can kill because the brain reacts differently to CO2 in the lungs in emphysema (reverse feedback than normal... normally we breathe in response to higher Co2 levels, triggering us to exhale and inhale).
