Unformatted text preview: (1) the total (barometric) pressure, and (2) the fractional concentration of that gas For example at sea level, the total pressure of all dry ambient (atmospheric) air gases equalsT-6Q qrll Hg which equals barometric pressure Composition of dry ambient air at sea level: &-Gas Concentration oz 20.93 % Nz 79.04 % coz 0.03 % 100.00 % 760.0 mm Hg The most imporlant factor determining gas exchange is the partial pressure gradients of the gases involved. Partial Pressure .2093 X760: 159.2 mm Hg .7904X760:600.7 mm Hg .0003 X 760: 0.1 mm Hg...
