Physiological dead space lungs
Total dead space (also known as physiological dead space) is the sum of the anatomical dead space and the alveolar dead space. Benefits do accrue to a seemingly wasteful design for ventilation that includes dead space. 1. Carbon dioxide is retained, making a bicarbonate-buffered blood and interstitium possible. 2. Inspired air is brought to body temperature, increasing the affinity of hemoglobin for oxygen, impr… WebbVOL 15 NO 4 ANESTHESIA OCTOBER 1960 Physiological dead space Changes during general anaesthesia Departments of Anasthesia and Experimental Medicine Guy's Hospital Recent work has demonstrated changes which suggest abnormal dis- tribution of gas and blood in the lungs, as a result of artificial ventila- tion in patients under general anasthesial.

The Bohr equation, named after Danish physician Christian Bohr (1855–1911), describes the amount of physiological dead space in a person's lungs.
