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 ...
Haldane's approach to decompression modeling was used from 1908 to the 1960s with minor modifications, primarily changes to the number of compartments and half times used.
