The two types of dead space are anatomical dead space and physiologic dead space. ![]() The alveolar dead space increases with age, affecting arterial oxygen without impairing the carbon dioxide elimination. Types of Dead Spaceĭead space from equipment, such as tubes ventilator circuitry. Bookshelf ID: NBK482501 Excerpt Dead space represents the volume of ventilated air that does not participate in gas exchange. The lung matures by age 2025 years, and thereafter aging is associated with progressive decline in lung function. Glomerular Filtration and Tubular Functionĭead space is the proportion of minute ventilation which does not participate in gas exchange. Because of the effects of dead space, the alveoli are ventilated by only 4 L of fresh gas each minute during inspiration, containing 840 mL of oxygen and little.
