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).
-Even a small increase of CO2 stimulates the CO2 receptors to cause a powerful stimulus to increase the rate and depth of respiration that overrides voluntary control. -O2 receptors are not as sensitive and require a 50% increase in O2 before causing a powerful increase in the rate and depth of respiration.
