Cuff Leak Test: Sensitivity and Specificity

Introduction: None written. Excerpt from the entry in Post-Extubation Stridor:
defined by an absolute leak volume < or = 110 mL

Other studies have given a range of sensitivity from 15-85% and specificity of 72-99%, e.g. PMID 12528025 and PMID 12209275. However, given the relatively low prevalence (5-12% in the studies cited), the positive predictive value would still be poor and the negative predictive value still rather good.
