The cuff-leak test may help to identify patients at risk to develop post-extubation laryngeal edema. However the discrimination power of the cuff-leak test is highly variable and can be use, at best, to detect patients at risk to develop edema but should not be used to postpone extubation as tracheal extubation can still be successful in many patients with a positive test. In this editorial, the author discuss the factors influencing the leak and hence its predictive value. Keywords extubation failure, laryngeal edema, stridor Tracheal extubation of patients is still a major challenge, with stridor (ranging from to 4% to 38%), the method of the possibility of post-extubation stridor and then re-intubation determination of cuff leak (absolute value versus value if the patient is unable to sustain the increase in respiratory relative to tidal volume measured with an inflated cuff, work. Stridor is responsible for 15–38% of extubation failures number of measurements of tidal volumes averaged, and so [1–3] and for close to 38% of early extubation failures [3]. on). But perhaps more importantly, the cut-off value should Recognition of stridor is important b
