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. Nitrogen dioxide poisoning depends on the duration, frequency, and intensity of exposure.
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 ...
With paroxysmal nocturnal dyspnea specifically, it is felt while sleeping and causes a person to wake up after about 1 to 2 hours of sleep. [ 3 ] More serious forms of dyspnea can be identified through accompanying findings, such as low blood pressure, decreased respiratory rate, altered mental status, hypoxia, cyanosis, stridor, or unstable ...
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.
Third-hand smoke is contamination by tobacco smoke that lingers following the extinguishing of a cigarette, cigar, or other combustible tobacco product. [1] First-hand smoke refers to what is inhaled into the smoker's own lungs, while second-hand smoke is a mixture of exhaled smoke and other substances leaving the smoldering end of the cigarette that enters the atmosphere and can be inhaled by ...
Exposure of the eyes and skin tends to be corrosive, causing blurred vision and severe deep burns. Inhalation of these agents causes burning of the throat, coughing, vomiting, headache, pain in chest, tightness in chest, and respiratory and circulatory failure. Examples of pulmonary agents include: Chlorine gas; Chloropicrin (PS) Diphosgene (DP)
Wind conditions, according to Cowlitz County, were “variable” in direction and speed up until 6 p.m., moving outside of the north and northwest part of the region from Longview towards ...
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.
