If my choice is between definitely dying of boring old hypoxia and maybe dying in a cool explosion I know which one I'm picking.

But to be serious it's risk management and if the patient is definitely going to die of low oxygen then the patient having a risk of dying another way is still a lower risk.

If I'm going to die from a small internal explosion, I'd rather it start at the other side of the tube. If my guts explode, I might still have a few more days to live.
