Straight measured SvO2 by the PAOC is definitely the criterion common against which calculation of SvO2 from PvO2 by BGA is judged. Strategies: We investigated the accuracy of SvO2 determination amongst BGA (AVL 995-Hb) and PAOC (Opticath, PA Catheter P 7110, Abbot) in 61 critically ill ICU individuals. We had 244 couples’ of SvO2 values simultaneously determined by the two distinct technologies. Final results: Benefits, descriptive statistics and correlation coefficients are shown the Table. The distinction among measured and calculated SvO2 was statistically substantial (P < 0.000). Conclusions: Calculation of SvO2 using BGA technology is always higher than PAOC SvO2 direct measurement by 1.6 . Although this difference is statistically significant (P < 0.00) the correlation between the two methods is quite high (r = 0.828, P < 0.01). BGA significantly overestimates SvO2 in comparison toTable Method Blood gas analysis Oximetric PA catheter X ?SEM 70.3 ?0.65 PubMed ID: 68.7 ?0.61 P (t-test) 0.000 r* 0.828 R2 0.*Correlation is substantial in the 0.01 level (2-tailed).PAOC. These benefits suggest that calculated SvO2 may well affect therapeutic choices in comparison to directly measured SvO2 since the slope with the oxyhemoglobin dissociation curve is extremely steep within the usual SvO2 range and as a result smaller changes inside the determination of PvO2 will result in relatively large modifications in calculated saturation [1]. Also, minor calculated hemoglobin saturation variations within this steep part of the curve represent major differences in hemoglobin O2 carrying capacity. Reference:1.

We prospectively evaluated the accuracy of cardiac output (CO) measurements of a new device for continuous CO monitoring determined by transpulmonary thermodilution detected within a femoral artery line against the identified gold common of a PA catheter. Solutions: Ten individuals presenting with high-grade aneurysmal subarachnoid hemorrhage had been monitored in their postoper.
