Thus, the Haldane effect describes the ability of hemoglobin to carry increased amounts of carbon dioxide (CO 2) in the deoxygenated state as opposed to the oxygenated state. Vice versa, it is true that a high concentration of CO 2 facilitates dissociation of oxyhemoglobin, though this is the result of two distinct processes (Bohr effect and ...
The Haldane effect: most carbon dioxide is carried by the blood as bicarbonate, and deoxygenated hemoglobin promotes the production of bicarbonate. Increasing the amount of oxygen in the blood by administering supplemental oxygen reduces the amount of deoxygenated hemoglobin, and thus reduces the capacity of blood to carry carbon dioxide.
Haldane's decompression model is a mathematical model for decompression to sea level atmospheric pressure of divers breathing compressed air at ambient pressure that was proposed in 1908 by the Scottish physiologist, John Scott Haldane (2 May 1860 – 14/15 March 1936), [1] who was also famous for intrepid self-experimentation.
The Bühlmann decompression model is a neo-Haldanian model which uses Haldane's or Schreiner's formula for inert gas uptake, a linear expression for tolerated inert gas pressure coupled with a simple parameterised expression for alveolar inert gas pressure and expressions for combining Nitrogen and Helium parameters to model the way inert gases enter and leave the human body as the ambient ...
While inhaling air is critical to supply cells with oxygen for aerobic respiration via the Bohr effect and Haldane effect (and perhaps local low oxygen partial pressure e.g. active muscles), [32] exhaling the cellular waste product carbon dioxide is arguably the more critical aspect of respiration.

John Scott Haldane CH FRS [1] (/ ˈ h ɔː l d eɪ n /; 2 May 1860 – 14/15 March 1936) was a Scottish physician physiologist and philosopher famous for intrepid self-experimentation which led to many important discoveries about the human body and the nature of gases. [2]
Frederick Duncan Michael Haldane (born 14 September 1951), [2] known as F. Duncan Haldane, is a British-born physicist who is currently the Sherman Fairchild University Professor of Physics at Princeton University. He is a co-recipient of the 2016 Nobel Prize in Physics, along with David J. Thouless and J. Michael Kosterlitz. [4] [5] [6]
