The effect of smoking five non-nicotine cigarettes and of breathing carbon monoxide on exercise-induced angina was evaluated in 12 patients with angina. Smoking increased venous carboxyhemoglobin from 1.71 to 5.35%, decreased exercise duration until angina 45%, increased ischemic ST-segment depression at angina from 1.33 to 1.52 mm, and decreased systolic blood pressure times heart rate at angi...

CORRESPONDENCE MANAGEMENT OF CARBOXYHAEMOGLOBINAEMIA Sir,—Drs Vegfors and Lennmarken have demonstrated usefully how easy it is to be misled in the management of carbon monoxide poisoning [1]. Their case deserves further comment. Unfortunately, there is little information on the mechanism of cellular toxicity of carbon monoxide. Carbon monoxide binds to haem-containing enzymes such as cytochrome...

Little quantitative monitoring and evaluation of the impacts of improved stoves have been performed in Mexico. Grupo Interdisciplinario de Tecnología Rural Apropiada (GIRA) has recently disseminated 4,000 improved Patsari cookstoves, most of them in the Purépecha region of Michoacán state, Mexico. In paired comparisons in a subset of kitchens in a single community before and after installation ...

Carbon monoxide intoxication is one of the most common types of poisoning in the world. Cardiac manifestations after exposure to carbon monoxide including myocardial ischemia, heart failure and arrhythmias have been reported. A 17-year-old woman was admitted to the emergency service with the complaints of palpitation, headache and nausea. Electrocardiogram revealed supraventricular tachycardia....

Portable generators are commonly used during electrical service interruptions that occur following large storms such as hurricanes. Nearly all portable generators use carbon based fuels and produce deadly carbon monoxide gas. Despite universal warnings to operate these generators outside only, the improper placement of generators makes these devices the leading cause of engine related carbon mo...

The Measurement of Pollution in the Troposphere (MOPITT) instrument was launched on the Terra satellite in 1999. It now provides an unprecedented decadal record of carbon monoxide (CO) from space. This important tropospheric trace gas is an excellent indicator of combustion processes, both from anthropogenic urban regions and biomass burning, and serves as a proxy for the study of pollutant tra...

Narghile smoking is a traditional method of tobacco use, and it has been practiced extensively for 400 years. Traditionally, narghile smoking is a matter of culture mainly in Middle East, Asia, and Africa. In recent years, its use as a social activity has increased worldwide, especially among young people. Narghile smoking is an unusual cause of carbon monoxide poisoning. Narghile smoking, comp...
