Sedating cats for airline travel
" And then added: "I don't want you to do that anymore." Stubbs is one of a special breed of researchers who pioneered aviation medicine in Canada and, indeed, worldwide.
In Canada, it all started with one man—an iconic figure whose name is instantly familiar to many Canadians, though usually not in the context of aviation medicine.
Nobel Prize winner Sir Frederick Banting, the co-discoverer of insulin, was head of the University of Toronto's Banting and Best Institute for Medical Research as war loomed in Europe.
The pressure also supports the arteries that carry blood from the heart.
Both effects enhance the heart's ability to pump blood up to the eyes and brain even under considerably increased G loads.
The question immediately came to mind: could this work for humans as well?
The idea was that the water—which, like blood, gets heavier when subjected to G forces—would exert sufficient pressure against tissues in the lower part of the body to prevent blood from pooling in the veins of the calves, thighs and abdomen, thus allowing the blood to return to the heart in a more nearly normal way."There were no human experimentation rules then—we did what we liked," he said. They felt you were part of the team." In a very real sense, these men are also part of the team that today includes astronauts and cosmonauts."This is a time when we were trying to learn how to do things." A former . The work they did on anti-gravity suits, pressure suits, helmets and oxygen masks, ejection seats, decompression sickness and motion sickness are all relevant to flying in space and their research laid a solid foundation on which today's operational space medicine program is based.These early researchers often served as their own guinea pigs, sometimes suffering serious injuries as a result.Stubbs, for example, broke his neck while testing ejection seats. That's what your job was for—to protect the aircrew.One G is the force exerted by earth's gravity, which is measured as weight.Thus, objects subjected to three Gs weigh three times their normal weight. It's not surprising, therefore, that the heart has trouble pumping it out of the body's extremities and up to the brain.) pilots with protection while flying at high altitudes.The research that was done by Canadian scientists during that time laid a solid foundation on which today's operational space medicine program is based.The military considered this one of the most pressing problems affecting the performance of their pilots; James told the scientists that it would provide an enormous tactical advantage if the G tolerance of the Allied pilots could be increased.The blackouts were a consequence of increased G-forces created by changes in speed and/or direction.
