PMCID: PMC471848  PMID: 5680242

Abstract

A nomogram for calculating venous shunt has been devised. The details of the derivation of the shunt formula according to which the nomogram is prepared have been reviewed. The simplicity of shunt study using the O2 breathing method and the example for using this nomogram are described.
