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).
Physiology [edit]. 1. Bronchoconstriction is due to an activation of parasympathetic nervous system. Postganglionic parasympathetic fibers will release acetylcholine (ACh) next to the Reissessen muscle, a smooth muscle layer surrounding the bronchi. These smooth muscle cells have M3 type muscarinic receptors on their membrane.
