PeCO2 is the partial pressure of CO2 in expired gas PaCO2 is arterial partial pressure of CO2 Physiological dead space can be calculated using Bohr's equation: Alveolar dead space is the volume of alveoli that are ventilated but not perfused (or underperfused), and anatomical dead space is the volume of the respiratory system from the nose and mouth to the level of the distal airways at which gas exchange begins to take place. 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
