Document Summary
Breathing pattern: minute ventilation v"e & breathing pattern. Tidal volume vt & frequency fr. Ventilation v"e: alveolar ventilation v"a & breathing pattern. Same minute ventilation v"e & dead space ventilation v"d. From rest to exercise = want deep & slow pattern. So body volume 1st & frequency later. *frequency fr will minimize alveolar ventilation v"a so maximize w/ tidal volume vt. Eventually = increase too much tidal volume vt so elastic recoil & wob work of breathing. Increase more tidal volume vt than frequency fr. Diffusion of gases = maintly determined by driving pressure gradient to prevent respiratory muscle stealing from exercising muscle. Total pressure of gas mixture = equal to sum of pressures that each gas would exert. Independently sum of partial pressures of individual gases in mixture. Partial pressure = % concentration of specific gas total pressure of gas mixture: percent & partial pressures of gases in dry ambient air - sea level.
