Scuba diving and dissolved air/nitrogen/oxygen in blood?
« on: November 10, 2007, 11:06:43 AM »
Given that SCUBA divers can get the "bends" if they don't resurface slowly, so: A diver is 33 meters below the surface of the ocean, where the temperature is 25 °C.  1) Determine the amounts of dissolved O2 and N2 (i.e. they are gases dissolved in a liquid solution) in the diver's 8 liters of blood volume.
2) What is the total vol. of dissolved air at 33 meters below the ocean?
3) What is the surface volume of O2 and N2 dissolved in this blood (at 1 atm).
4) What is the change in the vol. of dissolved gases when moving from -33 meters to the surface (0 meters)?  Of course, going from depth to surface causes the bends.

Thanks.

P.S. this is not an assigned homework problem
