Fig. 2From: Can perioperative hemodilution be monitored with non-invasive measurement of blood hemoglobin?Three experiments with different slopes. Distances between the marks are set equal in each subplot to facilitate comparison. a Flat slope. The non-invasive Hb changes much less than the invasive Hb. b Normal slope. The rise in non-invasive Hb is similar to the rise of the invasive Hb. c Steep slope. Greater increase in non-invasive Hb than for the invasive technologyBack to article page
