Question

Quizplus · Accepted Answer

The use of dapsone causes an increase in metHb,which will interfere with the accuracy of a pulse oximeter.The presence of metHb will decrease the actual saturation of Hb.Therefore,direct measurement of O₂Hb is most appropriate in this case.A CO-oximeter will not only measure the O₂Hb,but it will also measure the metHb level.
