A retrospective, off-line study of the relationship of the area under the intrauterine pressure waveform (Area) to amplitude was performed on contractions from patients in normal labor and hypocontractile labor before and during oxytocin therapy. A linear correlation of Area and amplitude can be identified in the study of large numbers of contractions. Unfortunately, the wide scatter of the values of either measure for a narrow range of values of the other precludes the use of Area as a clinically useful aid in assessing hypocontractility or oxytocin response from small numbers of contractions.
对正常分娩和宫缩乏力患者在催产素治疗前后的宫缩情况进行了一项回顾性离线研究，以探讨子宫内压力波形下面积（面积）与振幅之间的关系。在大量宫缩研究中可发现面积与振幅呈线性相关。遗憾的是，对于另一指标的窄值范围，任一指标值的广泛离散使得在根据少量宫缩评估宫缩乏力或催产素反应时，无法将面积用作临床上有用的辅助指标。
