    Hypotension indicates a decrease in blood pressure requiring intravascular fluid infusion ordered by the PSU physician; hypoxemia, a pulse oximetry reading <93% (in patients already receiving supplemental oxygen) or, for children with cyanotic congenital heart lesions, significantly lower than baseline; apnea, >10 seconds of no respiratory effort; airway obstruction, coughing, upper airway noise with respiratory distress; agitation, paradoxical agitation or movement after receiving sedation/analgesia; seizure, self-limited generalized tonic-clonic activity similar to known baseline seizures, not related to hypoxemia; hiccups, intractable hiccups after sedation producing head movement that prevented study completion; hypertension, blood pressure rise requiring treatment ordered by the PSU physician; emesis, emesis post sedation which prevented PO intake and necessitated admission to the hospital overnight.
