Abstract:
Exposure to a shock wave generated during an explosion may result in pulmonary trauma. For short-duration shock waves, the maximum of incident impulse is known to be correlated with the lung injury level of unprotected biological models. This study aims to correlate parameters related to large animal chest response under blast loading with a pulmonary injury level, which leads up to determine parameters which are themselves correlated with the maximum of incident impulse. Two groups of six post-mortem swine (PMS), lying on the ground, were exposed to shock waves of increasing intensity but constant positive-phase duration: 1.0 ms and 1.8 ms. Intra-thoracic pressure was recorded with a hydrophone placed into the esophagus while chest motion was obtained from an accelerometer screwed onto a mid-torso rib.
