We evaluate the fermion propagator in parity-conserving QED_3 with N
flavours, in the context of an IR domain approximation. This provides results
which are non-perturbative in the loopwise expansion sense. We include
fermion-loop effects, and show that they are relevant to the chiral symmetry
breaking phenomenon, that can be understood in this context.
