title: A flexible approach for on-line computerised quantification of intra-uterine pressure data.
abstract: 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.
