Abstract Background Splanchnic perfusion following hypovolemic shock is an important marker of adequate resuscitation. We tested whether the gap between esophageal partial carbon dioxide tension PeC02 and arterial partial carbon dioxide tension PaC02 is increased during graded hemorrhagic hypotension and reversed after blood reinfusion using a fiberoptic carbon dioxide sensor. Materials and method Ten Sprague-Dawley rats were anesthetized tracheotomized and cannulated in one femoral artery and vein. A calibrated fiberoptic PCO2 probe was inserted into the distal third of the esophagus for determination of luminal PeCO2 during maintained anesthesia pentobarbital 15mg kg per hour normothermia 38 C and .
