The following conditions must be observed if the actual pressure in the alimentary tract is measured and recorded with the aid of an open probe: 1. The probe must have a laterally placed opening, rather than a terminal one; 2. The opening must be as large as or larger than the internal diameter of the probe; 3. The internal diameter of the probe must be at least 1.2 mm or larger; 4. The pressure should not be measured with a nonperfusion technique if exact measurements of the intraluminal pressure are to obtained. One always has to use a perfusion, and the measured pressure depends on the speed of perfusion; 5. In order to be certain that the measured pressure corresponds to the actual pressure, one must ascertain whether the pressure will not change although the speed of perfusion is increased.
如果借助开放式探头测量并记录消化道内的实际压力，必须遵守以下条件：1. 探头必须有一个侧向开口，而不是末端开口；2. 开口必须与探头内径一样大或更大；3. 探头内径必须至少为1.2毫米或更大；4. 如果要获得腔内压力的精确测量值，不应使用非灌注技术测量压力。必须始终使用灌注法，且测量的压力取决于灌注速度；5. 为确保测量的压力与实际压力相符，必须确定尽管灌注速度增加，压力是否不会改变。
