Design outcomes

Primary

MeasureTime frame
The primary objective of the study was the measurement and comparison of safe apnea time. The mean apnea time for group A was 5.95 minutes with standard deviation of 0.29 minutes i.e. 17.4 seconds and that for group B was 5.94 minutes with standard deviation of 0.32 minutes i.e. 18.2 seconds. The p value was calculated using student t test which was 0.95, being more than 0.05, the value is not statistically significant.Timepoint: Apnea time—

Secondary

MeasureTime frame
As only one patient in each group desaturated, the resaturation time noted didnâ??t show significant difference. Resaturation time measurement was the secondary objective of the study.Timepoint: Resaturation time—
