Authors' Synopsis: The use of large doses of indocyanine green and of a multiple tailpiece sampling procedure is shown to increase both the range and sensitivity of photoelectric earpiece calibration. With these improvements in calibration technique, it becomes feasible to use a cardiac output computer to calculate the curve areas.
