Inhaling motor vehicle exhaust fumes is a common method used by people attempting to commit suicide; however, the decreased carbon monoxide concentrations found in the exhaust of late-model automobiles equipped with catalytic converters are changing the clinical presentation of exhaust inhalation.

There has been a decrease in both fatal and non-fatal intentional CO poisoning from motor vehicle exhaust since the 1980s, which correlates with reductions in vehicle CO emissions and is a likely result of the U.S. Clean Air Act of 1970 and the application of catalytic converters since 1975.

Motor Vehicle Exhaust Gas Suicide.

The study provides a review of countermeasures aimed at restricting this method of suicide, and found helpline signage at an exhaust-gassing suicide "hotspot" had some success in reducing suicides.

History, pathophysiology, clinical presentation and role of hyperbaric oxygen in acute carbon monoxide poisoning

The current concepts of the pathophysiology of carbon monoxide poisoning and the historical evolution of these concepts are reviewed and the clinical presentation is discussed as it relates to the various organ systems.

Apparent suicidal carbon monoxide poisonings with concomitant prescription drug overdoses.

We report four separate suicides by apparent motor vehicle-related carbon monoxide (CO) poisoning in which complete toxicological analysis showed the absence of, or lower than expected, percent

Trends in Suicide by Carbon Monoxide Inhalation in King County, Washington: 1996–2009

Trends of CO suicide in the ethnically diverse population of King County, Washington, U.S.A. are determined, indicating a possible shift in suicide trends that warrants further scrutiny in additional populations.

Determination of Carbon Monoxide Concentration in Industrial and Commercial Areas of Kano Metropolis, Kano State, Nigeria

The inco mplete co mbustion of organic fossil fuels such as oil, gas or coal is a common source of carbon mono xide (CO) pollution in the environ ment and when inhaled into the body it combines with

A Review on CO Oxidation Over Copper Chromite Catalyst

CO is a toxic and detrimental air pollutant. It not only affects human beings but also vegetation and indirectly increases global warming. An estimate has shown that vehicular exhaust contributes



Automobile Catalytic Converters

Publisher Summary This chapter reveals that the automobile catalytic converters have been used in the U.S. since 1974 (1975 model year vehicles) to meet regulated emission standards. In the early

Pathophysiology and treatment of carbon monoxide poisoning.

Oxygen therapy is the key treatment of carbon monoxide intoxication, and hyperbaric oxygen has been shown to interdict and improve clinical outcome in some patients, and immediate treatment with a high fraction of inspired oxygen and careful clinical evaluation are mandatory.

Of 2,360 victims of acute carbon monoxide intoxication examined between 1976 and 1981, delayed neurologic sequelae were diagnosed in 65 (2.75% of the total group, 11.8% of those admitted), with the peak incidence in the sixth and seventh decades.

Hemorrhagic necrosis and vascular injury in carbon monoxide poisoning: MR demonstration.

This case demonstrates characteristic findings on MR imaging of CO poisoning, as well as observations that suggest prior focal hemorrhage, and the role of vascular injury and prognosis are discussed.

Results provide a clear mechanism for the inhibition of CO-mediated brain lipid peroxidation by hyperbaric oxygen and indicate that hyperoxia causes a discrete disturbance of PMN adherence function.

Evidence for coronary spasm during flushing in the carcinoid syndrome

The observation of coronary spasm due to excess 5‐hydroxytryptamine (5‐HT) is discussed with regard to the discharge of 5‐HT from clotting platelets in the coronary arteries.

Expectoration of bronchogenic tumor tissue.

BRONCHOGENIC carcinoma can present itself in a variety of ways. Some patients with this disease may have an abnormal chest roentgenogram but no symptoms. Others may have manifestations of metastatic

In each of these patients symptom relief or improvement was obtained with expectoration of the unusual offending item—sponge, bullet fragment, shrapnel, "weck clips" (six), broncholith, tumor cast, and wax pack.

Expectoration of bronchogenic carcinoma.

Patients suspected of having pulmonary neoplasm should be instructed to save any grossly visible expectorated tissue fragments.
