However, these patients have problems oxygenating their blood because their damaged alveoli make them less able to absorb oxygen into the bloodstream and remove carbon dioxide from the blood. Greater. With emphysema, the lungs become increasingly compliant, due to alveolar destruction. As the alveoli are destroyed, air is trapped in the lungs, and TLC is increased. This makes these patients be more efficient at absorbing oxygen into their bloodstream and remove carbon dioxide from their blood. Smaller because these patients lungs' air sacs (alveoli) are damaged to the point that air gets trapped,ÿÿwhich decreases their lungs' residual volume as well as their total lung capacity.
