Acute inhalation injury may result from frequent and widespread use of household cleaning agents and industrial gases (including chlorine and ammonia).The airways and lungs receive continuous first-pass exposure to non-toxic and irritant or toxic gases via inhalation.
Smoke inhalation is the breathing in of harmful fumes (produced as by-products of combusting substances) through the respiratory tract. [1] This can cause smoke inhalation injury (subtype of acute inhalation injury) which is damage to the respiratory tract caused by chemical and/or heat exposure, as well as possible systemic toxicity after smoke inhalation.
Hippuric acid has long been used as an indicator of toluene exposure; [14] however, there appears to be some doubt about its validity. [15] There is significant endogenous hippuric acid production by humans; which shows inter- and intra-individual variation influenced by factors such as diet, medical treatment, alcohol consumption, etc. [15] This suggests that hippuric acid may be an ...
Acute chlorine gas poisoning primarily affects the respiratory system, causing difficulty breathing, cough, irritation of the eyes, nose, and throat, and sometimes skin irritation. Higher exposures can lead to severe lung damage, such as toxic pneumonitis or pulmonary edema , with concentrations around 400 ppm and beyond potentially fatal.
Nitrogen dioxide inhalation can result in short and long-term morbidity or death depending on the extent of exposure and inhaled concentration and the exposure time. Illness resulting from acute exposure is usually not fatal although some exposure may cause bronchiolitis obliterans, pulmonary edema as well as rapid asphyxiation. [40]
Acute hypercapnia is called acute hypercapnic respiratory failure (AHRF) and is a medical emergency as it generally occurs in the context of acute illness. Chronic hypercapnia, where metabolic compensation is usually present, may cause symptoms but is not generally an emergency.
A study of Montanans exposed to wildfire smoke for six weeks in 2017 found their lung function was impaired for at least two years following that exposure, Montrose said.
Repeated naphthalene exposure has also been found to potentially cause airway epithelial damage, aberrant repair, and inflammation. Greater numbers of peribronchial Mac-3-positive macrophages and CD3-positive T-cells were observed throughout the airways which displays acute inflammation within the airways. [17]
