A rapid, simple and low-cost method is presented for intracardiac left-to-right shunt quantification in children with congenital heart disease. The percentage of shunt is calculated from data obtained by continuous Po2 measurement during oxygen inhalation, using a nondisposable intravascular Po2-electrode cardiac catheter.

These values are compared with those obtained by the dye-dilution method (correlation coefficient r=0.89) and the Fick method (correlation coefficient r=0.98).

The Po2 measurement proved reliable for small, medium, and large sized shunts.
