Unformatted text preview: ngs is under 1 atmosphere of pressure and the diver breathes air that contains atmospheric partial pressures of N2 and O2 (79% and 21%, respectively). Ideally, a diver's air tank also contains a mixture of 79% N2 and 21% O2. Calculate the 1) volume of the diver's lungs as a function of lung volume at sea surface and 2) the partial pressures of N 2 and O2 for each of the following conditions: a. At 33 ft below the sea surface, the pressure on the diver's body is 2 atm. b. At 66 ft below the sea surface, the pressure on the diver's body is 3 atm. c. At 99 ft below the sea surface, the pressure on the diver's body is 4 atm. d. At 264 ft (should be 231 ft) below the sea surface, the pressure on the diver's body is 8 atm. The maximum O2 partial pressure (PO2) the huma...
