Utilising simple mathematical techniques of differential calculus, a computer program has been developed for real time, on-line processing of uterine contractions with a small computer. The area under the intra-uterine pressure--time curve is calculated and two distinctive values of this area are printed on-line every 512 sec. The 'active area', which is the area above the resting tone, is calculated in addition to the 'total area'--that is, the area above 0 mmHg. This allows an objective and efficient assessment of uterine activity which may be used as a basis of comparison between individual patients and groups of patients.
利用微分学的简单数学技术，已开发出一种计算机程序，可通过小型计算机对子宫收缩进行实时在线处理。计算子宫内压力-时间曲线下的面积，并每512秒在线打印该面积的两个不同值。除了“总面积”（即高于0 mmHg的面积）之外，还计算“活动面积”，即高于静息张力的面积。这使得能够对子宫活动进行客观有效的评估，可作为个体患者与患者群体之间比较的基础。
