![]() Blast injury : due to rapid heating and expansion of surrounding air.Low-voltage sources ( 10 6 V) electrical discharge → flashover effect (most of the current travels along the outside of the body) → lower risk of deep tissue injury compared with other electrical injuries.High-voltage sources ( ≥ 1000 V): e.g., lightning strike, industrial devices, power supply lines, conducted electrical weapon ( CEW).Workplace-related electrical injuries cause approx.Adults: most often found in occupational settings.Children: most often a household injury.4% of admissions to specialized burn services. Electrical injuries account for approx.Work-related respiratory conditions, e.g.:Įlectrical injury Epidemiology.Injuries related to changes in ambient pressure Frostbite and nonfreezing cold injuries.OverviewĮlectrical, thermal, and radiation injury Other environmental pathologies are covered in separate articles see “ Overview of environmental pathologies” for links. Treatment is usually conservative but rare, life-threatening complications (e.g., pneumothorax) may occur.Īgricultural health hazards include green tobacco sickness and anhydrous ammonia poisoning. Barotrauma is caused by a large pressure difference between the ambient environment and air-filled structures such as the middle ear, sinuses, and/or lungs. Treatment involves 100% oxygen and hyperbaric oxygen therapy ( HBOT). Decompression illness is caused by the presence of gas bubbles in the blood or tissue and manifests as musculoskeletal pain, altered mental status, and/or circulatory collapse. Preventative measures include staged ascent and prophylactic medications.ĭiving-related illnesses are caused by rapid changes in ambient pressure. Management involves descent, supplemental oxygen, and possible pharmacotherapy. Manifestations include acute mountain sickness, high-altitude pulmonary edema, and high-altitude cerebral edema. High-altitude illnesses result from inadequate acclimatization to the low partial pressure of inspired oxygen found at elevations > 2500 m ( ∼ 8000 feet). Management may include ATLS, ACLS, cardiac monitoring, and treatment of complications such as fractures. Individuals with an electrical injury require a thorough assessment for burns, cardiac complications (e.g., with a screening ECG), and traumatic injuries. Lightning injuries can manifest with fixed dilated pupils, cardiorespiratory arrest, and characteristic skin findings such as Lichtenberg figures. Send us feedback about these examples.Environmental pathologies are conditions caused by exposure to environmental factors such as extreme temperature, rapid changes in ambient pressure, electricity, wildlife, and environmental and occupational toxins and irritants.Įlectrical injuries typically manifest with burns, cardiac dysrhythmias, and/or traumatic injuries. These examples are programmatically compiled from various online sources to illustrate current usage of the word 'barometer.'

Giacomo Bologna, Baltimore Sun, 17 July 2023 But Monterey Car Week is also a barometer of sorts, gauging enthusiasm while establishing market trends-and values-within the collector community. Farnaz Fassihi, New York Times, 17 July 2023 Eight years after its sale fetched more than $66 million, the office tower at One South Street in downtown Baltimore sold last month for $24 million, a markdown that could be a barometer for the city’s commercial real estate industry. Elvia Limón, Los Angeles Times, 19 July 2023 Chicago wheat futures, a barometer for global prices, briefly jumped more than 4 percent as the Kremlin’s move jeopardized a key trade route to global markets for grain from Ukraine. Jarrett Bell, USA TODAY, 27 July 2023 This past week, many tuned in to see if its all-time temperature record of 134 degrees would be broken, a possibility that was heralded by some as a barometer of climate change. Recent Examples on the Web In any event, there may be no better barometer for Denver’s chances than Wilson, who signed a five-year, $245 million extension last year before taking a single snap in a Broncos uniform.
