Executive Summary

In the past years, there has been a dramatic transition between the use of older monophasic defibrillators to newer, more sophisticated, biphasic types. As these biphasic defibrillators are more efficient, they require less energy and therefore create less of a risk to bystanders. Due to the lack of research around these new defibrillators, the current recommended procedures may not accurately reflect the safety of medical personnel. Because of this, the recommended “all clear ” period may in fact become detrimental to the health of the patient as it causes the cessation of crucial activities of medical staff such as IV canalization and chest compressions. This thesis is aimed at assisting in a study to be performed by the Professor of Emergency Medicine at Royal Perth Hospital by designing a device capable of measuring, storing and analyzing the leakage voltages from a patient and their environment whilst undergoing defibrillation. The device that was designed consisted of a data acquisition system that would measure the voltages using standard ECG leads, and then wirelessly transmit that data to a laptop for further processing.
