Abstract:

The principal aim of this study was to evaluate current literature on noninvasive methods and instruments to provide recommendations on direction of technical development which could lead to a system or device for measuring vital signs of incapacitated military personnel in a toxic field environment. The specific aims of this study were 1 to determine the set of physiological parameters most likely to give the condition of an individual 2 to evaluate current noninvasive techniques and medical instruments to perform the desired life sign detection in a field environment without violating the integrity of the chemical protective garment and 3 to recommend areas of technological development that may lead to a noninvasive system or instrument for measurement or monitoring of vital life signs. The physiological measures primary vital life signs in order of priority are respiratory rate or frequency contents of respiratory sounds, heart rate from raw cardiac ECG signal or heart sounds, blood pressure, and core temperature. The most promising methodssystems in order of utility ranking were electromechanical measurements of respiratory and cardiac sounds, dry electrodes, and infrared technology. Biomagnetic field measurements offer the most advanced high technology area for noncontact, through the protective garment measurements of the magnetocardiogram. A second new technology area is bioelectric field measurements.
