This is the generator testing fixture for bipolar mode (vessel sealing). Two concentric aluminum rings submerged in a saline bath replicate the varying tissue impedance seen in human tissue during ...

It works by measuring the resistance (or impedance) of body tissues to a small electrical current that is passed through the body. While not 100% accurate, bioelectrical impedance analysis is ...

base impedance, which depends on thoracic blood and plasma volume, chest skeletal muscle, cardiac muscle, lung tissue, chest wall fat, and air; and 2) dynamic impedance, which is caused by ...
