Histotoxic hypoxia

Causes and Effects of Hypoxia – Video Transcript Today, we are going to talk a little bit about an aeromedical factor and that is hypoxia. The first thing that I want to do is talk a little bit about these symptoms like, what are the effects of hypoxia? Over here I have some of those effects and I want to walk through each of those, talk a little bit about them make sure we know what they are, and then what I want to do is dive into different types, or a better way to say that is maybe different causes, of hypoxia. As far as the effects are concerned, first one listed here is headache. I think everybody is familiar with what that is. Another common one would be impaired judgment or increased response time. So, you’re slower and you’re not really able to do things as quickly as you could, or you’re not really good at making good choices with the available information. Cyanosis is another common symptom. It’s when your lips or your fingernails get blue. Drowsiness and potentially something like numbness [are additional symptoms]. These are all effects of hypoxia and what’s interesting is different people tend to experience hypoxia differently, so really the only way that you would know is to have experienced it yourself as to which of these effects you’d be more prone to. A common example of what a lot of pilots would do in that case is visit something like an altitude chamber where they can depressurize this room and ultimately you can sort of experience the effects of hypo...

What Does This Mean for a Pilot? You’re trying to learn how to fly planes, not enter the medical industry right? I’m sure you are aware briefly of what happens to your body when you climb to higher altitudes. Though hypoxia for the average GA pilot may never prove to be something they experience (unless they are flying at higher altitudes that require supplemental oxygen), it is still very important information to know. Especially if you have chosen aviation as a career. I hope this information gives you a much better understanding of hypoxia and not just the basic knowledge needed to pass your check ride. If there are any specific questions you have about hypoxia, please feel free to The body requires oxygen to perform even the most basic functions. Without it, those functions cease to happen. The result of an imbalance between oxygen supply and the oxygen required of the body tissue is called hypoxia. Hypoxia is an illness caused by lack of oxygen reaching the tissue. In the most basic words to explain the definition of hypoxia, I would simply say that hypoxia is when a person doesn’t have enough oxygen. Types of Hypoxia Hypoxic Hypoxia Hypoxic Hypoxia occurs when there is an insufficient supply of oxygen all together. This can occur with things like a blocked airway or when one is drowning. However, we are more concerned with how this applies to us as a pilot right? As a pilot, we should know that at higher altitudes, there is a reduction in pressure. So though there is...

David R. Wallace, Aleksandra Buha Djordjevic, in An Introduction to Interdisciplinary Toxicology, 2020 20.3.3.3Cyanide 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. 66,67 CN also displays a high affinity for metal-containing enzymes and can inactivate superoxide dismutase (a major antioxidant enzyme), and nitric oxide synthase (the enzyme responsible for the production of the vasodilator nitric oxide). Alterations in cellular metabolism can increase production of lactic acid leading to acidosis. The primary sources of CN exposure are industrial processes such as processing and refinement of steel, pesticides, and most commonly cigarette smoke. 68 CN accumulates in plants in the form of cyanogenic glycosides and when ingested, CN can be released. 69 Consumption of foods high in cyanogenic glycosides may result in tropic ataxic neuropathy. 70 Previously, sodium thiosulfate and sodium nitrite were the primary antidotes available, but recently the use of dicobalt edetate, hydroxycobalamin, sulfanegen, and next generation sulfur donors have been developed as potential antidotes with higher potency and efficacy. 71–73 Isidro Ferrer, Noemi Vidal, in Handbook of Clinical Neurology, 2018 Abstract The chapter describes the epidemiology of cerebrovascular diseases, anatomy of the cerebral blood vessels, pathophysiology of ischemia, hypoxia...

Hypoxia is a medical condition in which some or all the tissues of the body do not receive a sufficient supply of oxygen from the blood. Various types of heart disease, unhealthy or afflicted blood, impaired circulation, or diseases affecting the lungs may all produce some form of hypoxia. Since oxygen is required throughout the body to sustain health, hypoxia can have serious consequences and requires immediate medical treatment. Symptoms of Hypoxia The symptoms of hypoxia include increased heart rate, changes in blood pressure, rapid breathing, shortness of breath, and a blue or ashen tint to the flesh due to the lack of oxygen. The condition can also affect the nervous system, and some people develop confusion and slurred speech. Four Types of Hypoxia There are four types: • hypoxemic hypoxia • anemic hypoxia • stagnant hypoxia • histotoxic hypoxia Even though they are all similar to each other and each type produces the same result, the way in which the process takes place is unique to each kind of hypoxia; the impairment of oxygen transfer from the lungs to the destination tissue occurs at different stages along the way. Hypoxemic Hypoxia In hypoxemic hypoxia, the oxygen level in the blood going to the tissues is too low to saturate the hemoglobin. The cause: a deficiency in the amount of oxygen available to breathe, often due to lower air pressure at high altitudes, or a failure in the lungs to properly transfer oxygen into the blood. Anemic Hypoxia In anemic hypoxia...
