A single gastric-esophageal probe, 5 mm in diam, with two transducers mounted near the tip has been used to measure transdiaphragmatic pressure in human subjects. The transducers are linear up to at least 200 cmH2O pressure and provide equal deflections for both positive and negative pressures. The method is shown to give results comparable to the standard procedure using two balloon-tipped catheters, one in the stomach and one in the esophagus.
一个直径为5毫米的单根胃食管探头，其尖端附近安装有两个换能器，已被用于测量人体的跨膈压。这些换能器在至少200厘米水柱压力下呈线性，并且对正负压力都能产生相等的偏转。结果表明，该方法所得到的结果与使用两根球囊导管（一根置于胃内，一根置于食管内）的标准程序相当。
