Best Answer: It means Brake Horsepower. It is an engine's horsepower measured without a loss in power caused by having all the accesories on in the car. Pretty much ...
Hypocapnic bronchoconstriction, induced by altering the concentration of CO2 in gas ventilating the lobe, was repeated in the presence and absence of various concentrations of anesthetic gases (halothane: 0.5, 1.0, and 3.0 per cent; enflurane: 1.0, 3.0, and 5.0 per cent; methoxyflurane: 0.25, 0.50, and 1.0 per cent).ypocapnic bronchoconstriction, induced by altering the concentration of CO2 in gas ventilating the lobe, was repeated in the presence and absence of various concentrations of anesthetic gases (halothane: 0.5, 1.0, and 3.0 per cent; enflurane: 1.0, 3.0, and 5.0 per cent; methoxyflurane: 0.25, 0.50, and 1.0 per cent).
Why would the chemical composition of the blood affect heart rate? Blood chemistry is determined, to a large extent, by the concentrations of gases in the blood. High carbon dioxide concentrations and low oxygen concentrations both indicate that gas exchange is occurring at a slower than ideal rate.The low rate of gas exchange could be due to rapid metabolism or to a low concentration of oxygen in the external environment.By monitoring blood chemistry the body is able to increase the heart rate and the rate of gas exchange to compensate.igh carbon dioxide concentrations and low oxygen concentrations both indicate that gas exchange is occurring at a slower than ideal rate.
