Abstract The pressure-induced intrinsic effects in the CuO2 plane within the van Hove singularity (VHS) scenario is combined with the modified two-dimensional (2D) lattice gas phenomenology for the basal plane to model the complex structure of the hole-doping dependence of the pressure derivatives of T c of YBa2Cu3O6+x . The experimentally observed structure is found to be reproduced reasonably satisfactorily in the present formalism. This shows that the pressure-induced changes in the CuO2 plane and the oxygen ordering in the basal plane both play important roles in explaining the doping dependent pressure derivative of T c .
