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 is the local control mechanism to try and keep ventilation and perfusion matched not good at altitude. because there is less PO2 overall in the lungs, leading to constriction of all arterioles, leading to less O2 carrying ability throughout the lungs.
