Background In this prospective observational study, we evaluated the effects of fluid bolus (FB) on venous-to-arterial carbon dioxide tension (PvaCO2) in 42 adult critically ill patients with pre-infusion PvaCO2 > 6 mmHg. Results FB caused a decrease in PvaCO2, from 8.7 [7.6−10.9] mmHg to 6.9 [5.8−8.6] mmHg (p < 0.01). PvaCO2 decreased independently of pre-infusion cardiac index and PvaCO2 changes during FB were not correlated with changes in central venous oxygen saturation (ScvO2) whatever pre-infusion CI. Pre-infusion levels of PvaCO2 were inversely correlated with decreases in PvaCO2 during FB and a pre-infusion PvaCO2 value < 7.7 mmHg could exclude a decrease in PvaCO2 during FB (AUC: 0.79, 95%CI 0.64–0.93; Sensitivity, 91%; Specificity, 55%; p < 0.01). Conclusions Fluid bolus decreased abnormal PvaCO2 levels independently of pre-infusion CI. Low baseline PvaCO2 values suggest that a positive response to FB is unlikely.

To the Editor.— Since publishing our article "Utility of an End-Tidal Carbon Dioxide Detector During Stabilization and Transport of Critically Ill Children (Pediatrics. 1992;89:1042-1044), it has been brought to our attention,1 and we also have observed that contamination of the end-tidal CO2 detector with gastric acid causes permanent yellow discoloration of the detector. The same is true of direct contact of the detector with resuscitation drugs (epinephrine, atropine, lidocaine).1 Such discoloration has not been observed with deep intratracheal drug administration.2,3
