阻抗容积图(impedance plethysmography)是企图通过人体电阻抗变化的测量来检测人体局部血液容积变化的一种技术。这种技术已在肢体血流检测等应用中获得成功,加之该技术具有简便、安全、可重复等特点,因而近些年来受到越来越多的重视。但是有关技术的理论基础与应用不断暴露出许多问题。尤其在用于胸部检测、企图反映心脏泵血活动时褒贬不一,结果也颇有争议。针对这些问题,第四军医大学生理学教研室臧益民教授指导其博士生 Impedance volume graph (impedance plethysmography) is an attempt to detect changes in the body’s local blood volume by a measure of changes in electrical impedance of the human body. This technique has been successful in applications such as limbs blood flow detection. In addition to its simplicity, safety and repeatability, the technology has gained more and more attention in recent years. However, the theoretical basis and application of technology continue to expose many problems. Especially for the chest test, trying to reflect the heart pump blood activity mixed, the result is quite controversial. In response to these questions, Professor Zang Yimin, Department of Physiology, Fourth Military Medical University guides its doctoral students
