By John T. Reeves, Robert F. Grover

John T Reeves and Robert F Grover have collected jointly seven episodes narrating the exploits of cutting edge researchers that ended in a few amazing clinical findings, changing the process drugs in Colorado and in the course of the international. From the summit of Pikes height to the mountains of Leadville and South Park, from the Maroon Bells above Aspen to the wonderful thing about south-western Colorado, every one episode is written by way of specialists on the subject of the unique experiments. Descendants, scientific colleagues, and those that have accordingly taken up the torch of study all supply exact perception into the heritage of technology above the timberline. excellent for wellbeing and fitness care execs attracted to the background of study at the human body's reaction to publicity at larger altitudes, this publication will intrigue mountain climbers, medical professionals, scientists, citizens of Colorado, and scientific historians.

Sample text

The third member of the original triumvirate of the fledgling Department of Veterinary Science in 1909, became the first head of the Department of Surgery and Clinics in 1934 and remained with the school as a clinical professor until his retirement. All three, Glover, Newsom, and Kingman, lived into their eighties and witnessed the growth and development of what is now Colorado State University’s College of Veterinary Medicine and Biomedical Sciences, one of the finest in the country for both teaching and research.

But he worried because the exposures were brief and might not tell the whole story. Three years later, in 1908, when he used longer exposure times in the altitude chamber at the Lister Institute in London, he began to get different results. When he exposed himself for twenty hours to low oxygen in the chamber at a simulated high altitude, there was a substantial fall in his carbon dioxide level, which was still apparent two days after he returned to the normal oxygen environment at sea level (Boycott A High Point in Human Breathing 29 and Haldane 1908).

Although Haldane didn’t measure lactic acid, he did speculate that it would increase. “During sudden and severe muscular exertion the circulation through the active muscles is insufficient to supply them with all the oxygen they require . . ” Once again he was correct, as confirmed years later by Dill’s group at Harvard (see chap. 5). On Pikes Peak, even with mild exercise, he found that breathing was strikingly enhanced and was almost twice that at sea level (fig. 6). As to why exercise should increase breathing so much at high altitude, he speculated that exercise had caused the oxygen level in the arterial blood to fall below the one at rest and furthermore that the exercising muscles produced more lactic acid at altitude than at sea level.
