After a long scuba diving session on a Caribbean reef, Carl boards a plane to Dallas. He begins to feel pain in his elbow on the flight back to Dallas. What is happening to him?
What will be an ideal response?
Carl is experiencing decompression sickness, "the bends," due to several problems: (1) Applying Boyle's law, a lot of gas was forced into Carl's bloodstream during the dive and there was not sufficient time to decompress the excess before he boarded the plane. (2) The plane is not pressurized to sea level, which further reduced atmospheric pressure holding the gases in suspension (Henry's law). Carl should be to be transported to a hyperbaric chamber to be repressurized. This will reduce the volume of the gas bubbles in his arm so that normal circulation can resume.
