A Nomogram for Planning Respiratory Therapy

Abstract

A nomogram is presented which aids in monitoring and selecting therapy in the treatment of the patient with hypoxemia. It facilitates accurate bedside determination of total shunt fraction and estimation of the arterial oxygen tension (PaO2) attainable at inspired oxygen concentrations of 21 percent to 100 percent. The nomogram permits rapid consideration of changes in hemoglobin concentration, arteriovenous oxygen content difference, and shunt fraction on the PaO2. The uses of the nomogram in several therapeutic contexts are discussed.
