Detection and localization of internal haemorrhaging using electrical bioimpedance

Electrical bioimpedance is an effective measuring tool to provide quick, non-invasive, real-time results which will be applied to the detection of internal haemorrhaging. Experiments were performed on female Fancy Rats weighing 333?44g, and 10mL of porcine blood was injected abdominally over 3 minutes. Data was collected using an 8?8 needle electrode array at 5 kHz, and 95 kHz and sent to the BioParHom Z-Flow. A strong correlation was found between the electrode paths crossing directly through the blood injection site, showing a decrease of about ?0.17?0.1?/mL for the 5 kHz frequency. This correlation allows us to quickly detect internal haemorrhaging and also localize it with the current path set-up in the electrode array.
