THORACIC ELECTRICAL BIOIMPEDANCE MEASUREMENT OF CARDIAC OUTPUT

本研究的目的是确定是否弹性支撑袜 将显著降低心输出量减少的程度 当孕妇站立时。此外，支撑袜可 显著降低子宫活动的频率， 从仰卧位变为站立位。 孕妇接受检测 没有支撑袜，要求在所有过程中穿着支撑袜， 醒着一周，然后重新测试。 截至目前，约1/4 预计将有40名参与者进行研究。 征聘 这个项目已经被证明是困难的，但我们将尝试招收 来年的研究人口平衡。

The objective of this study is to determine if elastic support stockings will significantly reduce the degree to which cardiac output decreases when pregnant women stand. In addition, support stockings may significantly reduce the frequency of uterine activity which follows the change from the supine to standing position. Pregnant women are tested without support stockings, asked to wear the support stockings during all waking hours for one week, and then retested. To date, approximately 1/4 of the anticipated 40 participants have been studied. Recruitment for this project has proven difficult but we will attempt to enroll the balance of the study population in the coming year.
