Pulmonary toxicity is the medical name for side effects on the lungs. Although most cases of pulmonary toxicity in medicine are due to side effects of medicinal drugs, many cases can be due to side effects of radiation (radiotherapy). Other (non-medical) causes of pulmonary toxicity can be chemical compounds and airborne particulate matter.
Oxygen toxicity is a condition resulting from the harmful effects of breathing molecular oxygen (O 2) at increased partial pressures.Severe cases can result in cell damage and death, with effects most often seen in the central nervous system, lungs, and eyes.
Many people with chronic obstructive pulmonary disease have a low partial pressure of oxygen in the blood and high partial pressure of carbon dioxide.Treatment with supplemental oxygen may improve their well-being; alternatively, in some this can lead to the adverse effect of elevating the carbon dioxide content in the blood (hypercapnia) to levels that may become toxic.
Partial pressures of inhaled oxygen exceeding 0.6 bar (FIO2 >0.6 at normal atmospheric pressure), administered for extended periods in the order of days, are toxic to the lungs. This is known as low-pressure oxygen poisoning, pulmonary toxicity, or the Lorrain Smith effect.
Higher exposures can lead to severe lung damage, such as toxic pneumonitis or pulmonary edema, with concentrations around 400 ppm and beyond potentially fatal. Chronic exposure to low levels can result in respiratory issues like asthma and chronic cough. Common exposure sources include occupational settings, accidental chemical mixing, and ...
Nitrogen dioxide poisoning is the illness resulting from the toxic effect of nitrogen dioxide (NO 2). It usually occurs after the inhalation of the gas beyond the threshold limit value. [1] Nitrogen dioxide is reddish-brown with a very harsh smell at high concentrations, at lower concentrations it is colorless but may still have a harsh odour.
