WebApr 8, 2014 · The increase in end-expiratory volume prevents alveolar collapse on exhalation, thereby maintaining ventilation–perfusion ratios and improving oxygenation. Figure 4. The relationship between respiratory system transmural pressure and volume in ( A ) a healthy subject and ( A – C ) in a patient with diffuse alveolar filling and reduced ... 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.

Physiological dead space and alveolar ventilation in ventilated infants. ... WebAlveolar ventilation prevents carbon dioxide buildup in the alveoli. There are two ways to keep the alveolar ventilation constant: increase the respiratory rate while decreasing the tidal volume of air per breath (shallow breathing), or decrease the respiratory rate while increasing the tidal volume per breath. simply 60
