Blood volume measurements using an integrated fiberoptic monitoring system in a porcine septic shock model.

Objectives: To compare the accuracy of an integrated fiberoptic monitoring system using transpulmonary thermo-dye dilution technique to measure blood volume (BV) with standard method using chromium-51-tagged erythrocytes in septic shock.

Design: Prospective blinded animal laboratory study.

Setting: University department of anesthesiology.
