We investigated the effect of capnography on the incidence of hypoxia in mildly obese patients undergoing EGD and colonoscopy by sedation. We found that early intervention based on capnography reduced the incidence of hypoxia in patients and kept SpOThere is a positive association between suppression of muscle activity and increased wet trapping of the upper airway with increasing doses of propofol [Another randomized study [Shao LJ et al. [A prospective cohort study [Our study has some limitations. Firstly, the depth of sedation using the bispectral index (BIS) was not recorded during the study. In theory, more profound sedation would increase how hypoxic the episodes in subjects would be. Chen et al. demonstrated a considerable lag between the BIS and MOAA/S scores, especially during the initial titration and recovery from sedation [
