We touched base on what can happen at depth under the water in our Dive Emergencies episode, but what happens if we head in the opposite direction? High altitude illness is divided into three presentations: Acute Mountain Sickness (the most common), high altitude pulmonary edema (HAPE) and High altitude cerebral edema (HACE). All are caused by a lower oxygen environment. How do we differentiate them and what do we do about it? All this and much more in this episode! Come get high with us! www.guardiantestprep.com
