Bioimpedance Analysis in Perioperative Assessment in Thoracic Surgery

"Bioelectrical Impedance Vector Analysis (BIVA) both in total body mode (Total Body Water) and segmental mode. The device used is the BIA 101 Anniversary by Akern. The BIVA exam will be performed in total body and segmental modes.~For total body mode, the patient should be placed on a non-conductive surface. After cleansing the skin with alcohol or mild soap, 4 electrodes will be placed: 2 on the right hand (metacarpal area) and 2 on the right foot (metatarsal). The cable connected to your instrument will then be connected to the electrodes. After the instrument is switched on, the variables are read and then analysed. For segmental mode, the patient should be placed on a non-conductive surface. After cleansing the skin with alcohol or mild soap, 8 electrodes will be placed: 2 on the right hand (metacarpal area) and 2 on the left hand, 2 on the right foot (metatarsal) and 2 on the left foot."
