Gastric lavage is contraindicated in corrosive acid poisoning like sulfuric acid poisoning. Bicarbonate is also contraindicated as it liberates carbon dioxide which can cause gastric dilatation leading to rupture of stomach, leading to severe abominal damage or death.
[12] [13] Furthermore, when phosgene hydrolyzes it forms hydrochloric acid, which can damage the cell surface and cause cell death in the alveoli and bronchioles. The hydrochloric acid triggers an inflammatory response that attracts neutrophils to the lungs, which causes pulmonary edema. [14]
Common sources of chemical burns include sulfuric acid (H 2 SO 4), hydrochloric acid (HCl), sodium hydroxide (NaOH), lime (CaO), silver nitrate (AgNO 3), and hydrogen peroxide (H 2 O 2). Effects depend on the substance; hydrogen peroxide removes a bleached layer of skin, while nitric acid causes a characteristic color change to yellow in the ...
The term immediately dangerous to life or health (IDLH) is defined by the US National Institute for Occupational Safety and Health (NIOSH) as exposure to airborne contaminants that is "likely to cause death or immediate or delayed permanent adverse health effects or prevent escape from such an environment." Examples include smoke or other ...
Sulfuric acid (American spelling and the preferred IUPAC name) or sulphuric acid (Commonwealth spelling), known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen, and hydrogen, with the molecular formula H 2 SO 4. It is a colorless, odorless, and viscous liquid that is miscible with water. [7] Structure ...
A new analysis from researchers at Harvard T.H. Chan School of Public Health has uncovered a microbial toxin in Juul pods that has the potential to cause serious longterm lung damage.
Nitrogen dioxide is sparingly soluble in water and on inhalation, it diffuses into the lung and slowly hydrolyzes to nitrous and nitric acid which causes pulmonary edema and pneumonitis leading to the inflammation of the bronchioles and pulmonary alveolus resulting from lipid peroxidation and oxidative stress. [25]
Lung symptoms in a patient who is taking a medicinal drug that can cause pulmonary toxicity should not automatically lead to a diagnosis of "pulmonary toxicity due to the medicinal drug", because some patients can have another (i.e., simultaneous) lung disease, e.g. an infection of the lungs not related to the medicinal drugs the patient is ...
