Question

Can a human die if submerged in highly oxygenated liquid water and breathe normal?

In: Biology

Answer 1

Water? Probably would die.

There have been experiments with liquid breathing, using liquid perflourocarbons, which has significantly higher O2 and CO2 holding capacity than water. It’s also easier to pull CO2 out of than water.

PFCs been used both medically (particularly neonatal), and professionally in a number of circumstances using both partial ventilation and full ventilation.
