WebAug 17, 2024 · The weight of dead space increases in proportion of tidal volume decrease. Secondly, the dead space which is the “wasted part of the breath” intervenes more frequently when respiratory rate increases. Alveolar ventilation (Valv) is the efficient part of the minute ventilation for gas exchange. Valv = RR x (V T-V D) = RR x V T – RR x V D WebFigure 22.3.1 – Boyle’s Law: In a gas, pressure increases as volume decreases. Pulmonary ventilation is dependent on three types of pressure: atmospheric, intra-alveolar, and interpleural. Atmospheric pressure is the amount of force that is exerted by gases in the air surrounding any given surface, such as the body.
