Measurement of blood loss by total-body counting on the basis of calculated and predicted blood volumes.
Blood loss was measured by total-body counting in conformity with the fall in activity, the calculated or predicted blood volumes being known. On the ground of the predicted and calculated blood volumes it was the Nadler formula which gave the best approximation. The method was employed for the measurement of blood loss in users of intrauterine contraceptive spirals. It was found suitable for the measurement of a sudden blood loss of major intensity.
