Altitude sickness

at high altitude causes several well-defined clinical diseases easily recognized by medical providers with experience in the mountains. These include acute mountain sickness (AMS), classic high altitude pulmonary edema (HAPE), and high altitude cerebral edema (HACE). These syndromes occur in mountain visitors ascending rapidly from low altitude or mountaineers at extremely high altitudes. Residents at altitudes above 2500 meters are not affected unless they travel and return to altitude, according

It is known that as altitude increases, atmospheric pressure decreases, as does the partial pressure of oxygen (Hall Table 44-1). That same table demonstrates that the partial pressures of both oxygen and carbon dioxide in the alveoli decrease as well. However, the alveolar water vapor pressure remains unchanged—constant at 47mmHg no matter the altitude (Hall 561). The most deleterious result of these factors is that less oxygen is being delivered to the tissues. Fortunately for me, Guyton and Hall

American-Israeli Cooperative Enterprise, n.d. Web. 12 Mar. 2016. .) It did change things about the military and how it used to be but too many were forced to die for this change. Dr. Sigmund Rascher Dr. Rascher was most known for his freezing and high altitude experiments. Freezing Experiments: Prisoner was put in ice freezing water, often tell they would shiver themselves to death. He did this to see how long German pilots shot down in the

went through indescribable pain as they were forced through high-altitude, freezing, tuberculosis, sea water, sulfanilamide, poison, and transplant experiments. Through these tragic Holocaust experiments, scientists and doctors discovered treatments used today for high-altitude sickness, hypothermia, contagious diseases, dehydration, poisoning, and war wounds. Jews were placed in low-pressure chambers to determine the maximum altitude from which the crews of damaged aircraft

unconsenting prisoners. Three of these experiments, conducted for the benefit of the German army, were: the High Altitude experiment, the Freezing Temperature experiment, and the Sea Water experiment. These experiments resulted in many scientific breakthroughs at the cost of the lives of thousands. The High Altitude experiments were experiments for German pilots to test human endurance at high altitudes both with and without oxygen. Victims were locked in a low-pressure chamber, to which the pressure was

illustrated through the unpredicted physical challenge because the climbers were so weak, they barely felt like humans. Although most of the climbers knew what the effects of the altitude would be, and many had climbed tall mountains before, the altitude sickness was much more severe than many had expected. The altitude also drove the climbers to such conditions that many would consider barely human. Jon Krakauer writes, “My appetite vanished

composition of oxygen in air remains constant only the atmospheric pressure to decrease with altitude. The respiration pattern should have shown a more frequent incidence of trough and crest, but the amplitude decreased with the increasing elevation, as the oxygen molecules contained in each breathe are low. Since less oxygen are presented the oxygen and carbon dioxide should decrease with increasing altitude. Equally since more breathe are taken to allow the body to be oxygenated, the heart would need

mmHg (altitude approx 14,115 ft.) • At this high altitude there will be a decreased PiO2, which will lead to decreased PAO2 and PaO2 tensions. The decreased air density, humidity and temperature at Pike’s Peak can lead to water loss, ventilatory changes and alternations in pulmonary hemodynamics. Decreases in pulmonary vasoconstriction through decreases alveolar oxygen tension, as well as increases in pulmonary vascular resistance and pulmonary artery pressure, are seen at this high altitude. •

the symptoms of what is called decompression sickness (DCS) this being a result from when he went scuba diving and then getting on a flight. For starters the person from being so deep in the reef, and where a good amount of gases went into his bloodstream when he was diving. After returning above the water his body did not have time to decompress the gases from his lungs. Meanwhile once the person boarded the plane and with the different altitudes within a short period of time. Taken in consideration

supposedly immune to such diseases. Krakauer states, “the sidar was adamant that Ngawang didn’t have HAPE or any other form of altitude illness, “but rather was suffering from ‘gastric,’ the Nepali term for stomach ache”” (Krakauer 115). If Ngawang was not Nepalis or a sherpa than the other sherpas would not have assumed that it was impossible for him to get altitude sickness. But it was presumed that all sherpas were immune to such illnesses since they were born in and lived in hose kinds of
