It includes both alveolar and anatomical dead space. LP101939-9 Physiological dead space The physiological dead space is the volume of gas in the respiratory system that is not involved in respiratory gas exchange. 60869-5 Physiological dead space Respiratory system -on ventilator Active Part Description
