Study outcome
hypoxia, apnoea
HYPOXIA, SECONDARY, RESPIRATORY DEPRESSION
Inadequate alveolar ventilation during sedation included altered ventilation, apnoea, or decreased oxygen saturation. The capnographic criterion for apnoea was the absence of exhaled COThe primary outcome was the incidence of hypoxia during sedation, defined as a decrease in SpOThe secondary outcomes included (i) incidence of subclinical respiratory depression (90% ≤ SpO
