The purpose of this research is to explore the current methods of fluid resuscitation and other possible methods of measuring the body fluid levels of burn patients in order to fully understand the fluid increase patterns in the torso area. This will be done primarily by focusing on the concept of bio-electrical impedance spectroscopy to measure the fluid levels only in the human torso area. Three similar tests were carried out by measuring the resistance values after ingesting 500ml of water. This was repeated until a total of 1500ml of water was ingested. It was found that the resistance in the extracellular fluid (R0) appear to not be significantly affected by the increase in fluid intake but the resistance in the intracellular fluid (R∞) show a greater difference. This can be due to a variety of conditions including the path flow of the ingested water content. The resistance measurements from the back of the torso posed to be more accurate than that of the front of the torso. This can also be connected to the water path flow. In order to further study the chosen electrode placements and understand the cause of the difference between the front and back torso results, more focused tests will be carried out in the future.
