The aim of the study was to evaluate leakage of liquid past the low‐pressure cuffs of tracheal tubes. Ten samples of each of nine different types of tubes were tested in a PVC mock trachea, using intracuff pressures of 20, 30, 40 and 50 cmH 2 O. In five types of tubes, 6–10 cuffs allowed profuse leakage (> 20 ml water in 5 min) even at the highest intracuff pressure, i.e. 50 cmH 2 O. In the most efficient tube, all the cuffs were leak‐proof (leakage < 5 ml in 5 min) at 40 cmH 2 O and in the second best type the cuffs were leak‐proof at 50 cmH 2 O. The leakage of fluid past the tracheal tube remains an unresolved problem with low‐pressure cuffs.
