ProSeal vs Classic laryngeal mask airway (LMA): Inadequate oxygenation (SaO₂ < 90% on peripheral oxygen saturation)
It is very uncertain whether proSeal changes inadequate oxygenation (SaO₂ < 90% on peripheral oxygen saturation) compared with classic laryngeal mask airway (LMA) (very low certainty).

How reviews are matched to this question
Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
