WebIn adults, anatomic dead space is 2.2 ml/kg. Because of the relatively large head size of infants and children, we hypothesized that extrathoracic and, therefore, total dead space would be relatively larger in pediatric subjects. Extrathoracic dead space was measured by a "water displacement" techni … Dead space is the volume of air that is inhaled that does not take part in the gas exchange, because it either remains in the conducting airways or reaches alveoli that are not perfused or poorly perfused. It means that not all the air in each breath is available for the exchange of oxygen and carbon dioxide. … See more Total dead space (also known as physiological dead space) is the sum of the anatomical dead space and the alveolar dead space.
