Table 1. Characteristics of cardiorespiratory function in victims after severe blunt chest injury (mean + SD).
PaO2 = arterial partial pressure of oxygen; PaO2/FiO2 ratio = ratio of the partial pressure of arterial oxygen to the fraction of inspired 100% oxygen. SVI = stroke volume index; CI = cardiac index; HR = heart rate. See text for definitions of phases 1-3. This table shows statistically significant differences of mean values after comparison of all phases and groups. Values are shown as mean (SD). *Significant differences between phases, P<0.05; **Significant difference between phases, P<0.01; ***Significant difference between phases, P<0.001. The number inside the brackets beside symbols represents phase number. †Significant difference between Groups A (or C) and B, P<0.05; ††Significant difference between Groups A (or C) and B, P<0.01; †††Significant difference between Groups A (or C) and B, P<0.001.
