Supplemental Oxygen for you

DID YOU KNOW THAT ...
An oxygen test tube is one of the most popular artifacts in Henry Ford Museum & Greenfield Village in Dearborn, Michigan. The story goes that it contains the last breath of the great inventor  Thomas Alva Edison. Immediately after Edison expired  in 1931 his doctor put several tubes up to Edison's lips to catch the carbon dioxide from his deflating lungs. The physician sealed each tube with paraffin and gave them to Charles Edison who knew that Henry Ford's idol was Thomas Edison. He  presented Ford with one of the tubes as a 'keepsake'. The museum acquired the tube after the death of Henry Ford and his wife Clara. However there is some discussion about how much carbon dioxide and how much oxygen currently is contained in the tube. How much of Edison's breath could be in the tube? Does it contain both oxygen and carbon dioxide? Fact is that this tube is an unconventional tribute to a great man.
