Until now, knowledge about what\u2019s happening to people at high altitudes has relied heavily on self-reporting and questionnaires.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That\u2019s not good enough.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Mostly because people lie, especially to themselves about how the environment is affecting them and especially when they\u2019re \u201ctough\u201d soldiers who don\u2019t want to admit anything affects them physically.<\/p>\n\n\n\t<aside class=\"smg-interstitial-link wp-block-smg-interstitial-link\">\n\t\t<a href=\"https:\/\/one.sightlinemg.com\/armytimes\/news\/your-army\/2018\/07\/30\/a-new-cold-war-how-the-army-is-preparing-for-a-fight-in-the-arctic\/\" class=\"smg-interstitial-link__inner\">\n\t\t\t\t\t\t\t<div class=\"smg-interstitial-link__media\">\n\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"225\" src=\"https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/ARM-arctic-cover-1-web.jpg.jpg?w=300\" class=\"smg-interstitial-link__image wp-post-image\" alt=\"\" \/>\t\t\t\t<\/div>\n\t\t\t\t\t\t<div class=\"smg-interstitial-link__content\">\n\t\t\t\t<span class=\"smg-interstitial-link__kicker\">Related<\/span>\n\t\t\t\t<h3 class=\"smg-interstitial-link__title\">A new cold war: How the Army is preparing for a fight in the Arctic<\/h3>\n\t\t\t\t\t\t\t\t\t<p class=\"smg-interstitial-link__excerpt\">Russia&#039;s Arctic buildup has gotten some attention from the U.S. military, but some say the Army is still unprepared for an extreme cold-weather fight.<\/p>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/a>\n\t<\/aside>\n\t\n\n\n<p class=\"wp-block-paragraph\">But a new Army tool  \u2014 the Acute Mountain Sickness-alert \u2014 may prove to be the first algorithm to successfully predict AMS risk in real-time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">And the tool should be transitioned to the U.S. Army Medical Materiel Development Activity at the end of 2022.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Army\u2019s Research Institute of Environmental Medicine took 41 soldiers from the 509th Clearance Company, 5th Engineer Battalion, out of Fort Leonard Wood, Missouri, to fighting altitude this past summer in Taos, New Mexico.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That trip was more than a nice mountain view-seeking selfie opportunity. Scientists used the trip to test how effectively they could predict who would get AMS.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">AMS can debilitate a person for up to 72 hours \u2014 impairing their thinking, plaguing them with nausea, headaches, fatigue, poor sleep and shortness of breath \u2014 which would render them ineffective or even a liability on a high-altitude mission.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Mountaineers and even soldiers from northern-based units, work through this by acclimatizing over days or weeks and living in the environment. That might mean climbing up a few thousand feet then sleeping slightly lower. They\u2019d follow that process, \u201ctwo steps forward, one step back,\u201d until soldiers reach the fighting area.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"4288\" height=\"2848\" src=\"\/wp-content\/uploads\/2026\/08\/DSC_0792_1.jpg.jpg\" alt=\"\" class=\"wp-image-45433\" srcset=\"https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/DSC_0792_1.jpg.jpg 4288w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/DSC_0792_1.jpg.jpg?resize=300,199 300w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/DSC_0792_1.jpg.jpg?resize=768,510 768w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/DSC_0792_1.jpg.jpg?resize=1024,680 1024w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/DSC_0792_1.jpg.jpg?resize=1536,1020 1536w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/DSC_0792_1.jpg.jpg?resize=2048,1360 2048w\" sizes=\"auto, (max-width: 4288px) 100vw, 4288px\" \/><figcaption class=\"wp-element-caption\">A soldier with the 509th Clearance Company, 5th Engineer Battalion, hikes at altitude near 12,000 feet to help researchers develop a tool for detecting altitude sickness. (Army)<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">That\u2019s nice, but not feasible for a heliborne mission from ship to shore to mountain, or from low-lying bases to high-altitude combat zones.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Another way they work through this is to \u201cpre-medicate\u201d soldiers with certain drugs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But those drugs have side effects and only reduced symptoms in about a quarter or third of those who take it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Another altitude crapshoot.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">And it\u2019s not just a few people who face this challenge. About half to as many as 90 percent of unacclimatized troops will experience some level of AMS while ascending to a high altitude, said Dr. Beth Beidleman, a research physiologist and the study\u2019s principal investigator.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Beidleman has been working on altitude problems for the Army for three decades and spoke with Army Times recently about current work and new advances.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It\u2019s frustrating for commanders because three people at 12,000 feet above sea level or higher can show vastly different reactions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Person A might be completely incapacitated, while person B has a minor headache, but can function. Meanwhile, person C is shooting baskets and running around like they\u2019re hanging out at the beach, she said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThere\u2019s a huge individual variability in the likelihood of experiencing AMS,\u201d she said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">And until now, there wasn\u2019t a clear way to know who would be affected in what way.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After this past summer\u2019s study, she said they\u2019ve validated that the AMS-alert tool can identify a high-risk person with an 83 percent accuracy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The ability goes beyond the comfort and care of individual soldiers. Logistics, for example, can be adjusted. Planners can take fewer oxygen bottles if they have a solid predictive tool to know they don\u2019t need to pack multiple bottles for each soldier, she said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThis is kind of like personalized medicine,\u201d Beidleman said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">ARIEM does have a research facility on Pikes Peak, Colorado, at 14,000 feet. But many military missions, especially in Afghanistan, took place at between 12,000 and 14,000 feet, she said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Taos Ski Valley fell right in that sweet spot.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"4288\" height=\"2848\" src=\"\/wp-content\/uploads\/2026\/08\/DSC_0486.JPG.jpg\" alt=\"\" class=\"wp-image-45435\" srcset=\"https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/DSC_0486.JPG.jpg 4288w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/DSC_0486.JPG.jpg?resize=300,199 300w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/DSC_0486.JPG.jpg?resize=768,510 768w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/DSC_0486.JPG.jpg?resize=1024,680 1024w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/DSC_0486.JPG.jpg?resize=1536,1020 1536w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/DSC_0486.JPG.jpg?resize=2048,1360 2048w\" sizes=\"auto, (max-width: 4288px) 100vw, 4288px\" \/><figcaption class=\"wp-element-caption\">Researchers with the Army&#8217;s Research Institute of Environmental Medicine examine samples to help detect Acute Mountain Sickness symptoms in soldiers working at high altitudes. (Army)<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Being able to bring soldiers from a lower altitude, not acclimatized, like those stationed in Alaska, or northern reaches of California and elsewhere, and immediately have them ascend, gave researchers a realistic way to see how rapidly deployed troops might react to a drastic change in oxygen levels.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There are other variables to consider. Sometimes soldiers come in at a higher altitude and work their way down to an objective. That\u2019s another area where the tool might be effective.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Work that Beidleman did with researchers at the Walter Reed Army Institute of Research is also checking the messenger RNA signal (instruction booklet for making proteins) in blood, urine and saliva to find out if there is a genomic component that could more accurately predict which individuals might experience AMS.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Scientists Dr. Rasha Hammamieh and Dr. Aarti Gautam are doing the work at Walter Reed. Dr. Phil Karl, also with ARIEM, is studying gut microbiome in relation to how it affects performance, and Dr. Mark Buller is working on physiological monitoring, Beidleman said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">And the Army\u2019s not alone here.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dr. Camilla Mauzy, with the Air Force Research Laboratory, is looking at the breakdown products of protein, fat and carbohydrates metabolism to predict individual susceptibility to AMS more accurately.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An early version of AMS-alert was tested with a group of 16 people. But the 2021 summer study had 41 soldiers, a larger sample size from which to gather data.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cWe can\u2019t just take eight to 10 people and say, \u2018this really works.\u2019 We need to study large populations of individuals,\u201d Beidleman said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Beidleman and her team are sifting through the reams of data they collected on their summer test, expecting to further validate and refine the AMS-alert tool.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers expect to have the tool to
