+ - Resumption of oxygen to cells kill cells

Submitted by Carlinya
Carlinya (622024) writes "Newsweek reports that standard emergency-room procedure has it backward by pumping oxygen to someone who's heart has stopped for more than a few minutes.

According to the article: "Once the cells have been without oxygen for more than five minutes, they die when their oxygen supply is resumed. The cellular surveillance mechanism cannot tell the difference between a cancer cell and a cell being reperfused with oxygen. Something throws the switch that makes the cell die.""
