A study of cricoid pressure was undertaken to relate the applied cricoid force with the resulting intraluminal cricopharyngeal (or oesophageal) pressure. The results indicate that whilst there was a wide range in normal adults a cricoid force of 44 N was judged to be effective in protecting the majority of adult patients from regurgitation.
开展了一项关于环状软骨压迫的研究,以将施加的环状软骨压力与所产生的环咽肌(或食管)腔内压力联系起来。结果表明,虽然正常成年人的范围很广,但44牛的环状软骨压力被判定可有效保护大多数成年患者不发生反流。
