Narcosis results from breathing gases under elevated pressure, and may be classified by the principal gas involved. The noble gases, except helium and probably neon, [2] as well as nitrogen, oxygen and hydrogen cause a decrement in mental function, but their effect on psychomotor function (processes affecting the coordination of sensory or cognitive processes and motor activity) varies widely.
Depending on the type and amount of irritant gas inhaled, victims can experience symptoms ranging from minor respiratory discomfort to acute airway and lung injury and even death. A common response cascade to a variety of irritant gases includes inflammation , edema and epithelial sloughing , which if left untreated can result in scar formation ...
Toxic gases, by contrast, cause death by other mechanisms, such as competing with oxygen on the cellular level (e.g. carbon monoxide) or directly damaging the respiratory system (e.g. phosgene). Far smaller quantities of these are deadly. Notable examples of asphyxiant gases are methane, [1] nitrogen, argon, helium, butane and propane
“This antidote will limit damage from gas poisoning caused by sudden fires and can be tested for the treatment of various symptoms caused by gas poisoning,” study co-author Hiroaki Kitagishi ...
Metal fume fever, also known as brass founders' ague, brass shakes, [1] zinc shakes, galvie flu, galvo poisoning, metal dust fever, welding shivers, or Monday morning fever, [2] is an illness primarily caused by exposure to chemicals such as zinc oxide (ZnO), aluminium oxide (Al 2 O 3), or magnesium oxide (MgO) which are produced as byproducts in the fumes that result when certain metals are ...
Decompression sickness can occur after an exposure to increased pressure while breathing a gas with a metabolically inert component, then decompressing too fast for it to be harmlessly eliminated through respiration, or by decompression by an upward excursion from a condition of saturation by the inert breathing gas components, or by a ...
Gas appliances are designed to vent CO outdoors, but if there’s a malfunction, they can leak it indoors and cause carbon monoxide poisoning. Breathing in a lot of CO can make you pass out, or ...
The origin of these symptoms was not clear; possibilities raised at the time included "a regional or bacterial disease or lead poisoning". [66] In 1955, cadmium was identified as the likely cause and in 1961 the source was directly linked to mining operations in the area. [67] In February 2010, cadmium was found in Walmart exclusive Miley Cyrus ...
