We have evaluated the Sonomatic Confirmation of Tracheal Intubation device (SCOTI) by testing its ability to be correctly configured with a variety of tracheal tubes of differing internal diameter and length. The device only configured correctly for RAE tubes with internal diameter of 7.0 mm or greater and for armoured tubes of internal diameter 8.5 mm. For conventional tubes of varying internal diameter cut to different lengths, configuration was only successful with certain dimensions. The inability to configure the device correctly with all types and lengths of tracheal tubes limits its usefulness as a indicator of tracheal intubation.
我们通过测试气管插管声控确认装置（SCOTI）与各种不同内径和长度的气管导管正确配置的能力，对该装置进行了评估。该装置仅能与内径7.0毫米或更大的RAE导管以及内径8.5毫米的铠装导管正确配置。对于切割成不同长度的各种内径的传统导管，仅在某些尺寸下配置才成功。无法与所有类型和长度的气管导管正确配置该装置限制了其作为气管插管指标的实用性。
