Teleost fish show important species-specific adaptability to O2 deprivation, moving from intolerance to a full tolerance of hypoxia and even anoxia. Alcohol narcotics and cyanide are three primary factors that can cause histoxic hypoxia. CN elicits toxicity by inhibiting cytochrome c oxidase, blocking electron transport in the mitochondria and ultimately oxygen utilization, resulting in a condition known as histotoxic hypoxia. No matter what the cause or type of hypoxia you experience, the symptoms and effects on your flying skills are basically the same. Carbon monoxide can also be a hypemic as well as a histoxic hypoxia. Hypoxic hypoxia results from a deficiency of O2 or reduced partial pressure in the air being inspired. Effects of Acute Hypoxia. This occurs with altitude because of decreased barometric pressure and is therefore most germane to aerospace medicine. Intake of certain poisons such as cyanide or hydrogen sulfide can also be a cause. Mood can also be affected at this stage. In cases of histotoxic hypoxia cells are damaged and are therefore unable to absorb and use oxygen. One factor that makes hypoxia dangerous is its insidious onset; your signs and symptoms may develop so gradually that they are well established before you recognize them.
