Abstract:
The instantaneous changes of the body cavities under the impact of blast waves were studied in three dogs. The changes were recorded with the high-speed photography of three different speeds (563, 1526, and 6526 frames/second). It was demonstrated that there was an 11.7% reduction on average of the body cavities due to compression after 0.777 kg/cm2 of overpressure was received.In correlation with the authors' previous research work and with the relevant literature, it is believed that the 11.7% reduction is likely related to the severe pulmonary injury which is resulted from the abrupt disturbance of hemodynamics after blast wave impact.
