A diver is on 30% Nitrox at 130 FSW. 15 minutes after reaching the bottom, while swimming near a peculiar outcropping of rock, a large octopus shoots out and locks a tentacle around his neck hard enough to completely close both carotid arteries, but somehow leaving the trachea partially open. The diver maintains a working regulator in his mouth. The tentacle cannot be loosened by any means. 180-240 seconds after the octopus grabs the diver, what will be the gas phase equivalent PPO2 concentration in his cerebral arterial blood supply in atmosphreres?
A. greater than 2.
B. about 1.5
C. between 0.3 and 1.5
D. less than 0.16
E. Cannot be determined from the information given.
At 240 seconds what is the gas equivalent PPO2 concentration in the coronary arterial circulation?
A. greater than 2.
B. about 1.5
C. between 0.3 and 1.5
D. less than 0.16
E. Cannot be determined from the information given.
