The purpose of the study — to identify and evaluate clinical significance “hidden” disorders blood oxygenation in smokers with exacerbation bronchial asthma. Materials methods: spirometry, pulse oximetry, CO-metry exhaled air. To diagnose oxygenation, including violations spectral characteristics level hemoglobin oxygen saturation, 19 male (middle age 54,6±2,05 years) mixed (68 %) or allergic (...

Acute exposure to environmental tobacco smoke (ETS) is considered to adversely influence atherogenesis. The aim of this article was to assess whether brachial ultrasonography in subjects with endothelial dysfunction after ETS exposure is associated with atherosclerotic lesions. Never smoker healthy volunteers (n = 18) and subjects with a previous myocardial infarction (MI; n = 10) were studied....

Five patients presented to the emergency department (ED) following exposure in an enclosed space to methylene chloride (dichloromethane), used for removing paint. Two workers and three rescuers were involved. Two rescuers complained only of dizziness and mild nausea, and were subsequently discharged from the ED. One rescuer was asymptomatic. Worker no. 1 arrived in cardiac arrest and eventually...

This study was conducted to determine whether or not a low concentration of carboxyhemoglobin influences the extent and severity of myocardial ischemia caused by coronary ligation. In 10 dogs, electrograms were recorded from 6 epicardial electrodes mounted on the anterior surface of the left ventricle and distributed over the area normally perfused by the lighted branch of the left anterior des...

BACKGROUND Dichloromethane poisoning affects predominantly the central nervous and the cardiovascular systems, and results from both carboxyhemoglobin formation and direct solvent-related narcosis. Exposure is frequently occupational and related to paint-stripping. Several reports have described severe adverse effects as well as fatalities. Conflicting reports regarding peripheral nerve toxicit...
