Comparison of mean exhaled tidal volume and mean EtCO2 in both groups
| Parameters | Group A n=66 Mean (SD) | Group B n=66 Mean (SD) | Mean difference (95% CI) | P |
|---|---|---|---|---|
| Exhaled tidal volume (ml) | 377.51 (82.79) | 476.71 (121.85) | 99.21 (63.34, 135.09) | 0.001 |
| EtCO2 (mmHg) | 28.83 (1.83) | 30.42 (2.59) | 1.576 (0.80, 2.35) | 0.001 |
CI=confidence interval, SD=standard deviation, n=number, EtCO2=End-tidal carbon dioxide
