Abstract:
Objective: To study the lung injury caused by se gmented shock waves. Methods: A total of 60 rabbits and 20 rats were used in this st udy. The process of transmission of shock waves was divided into three phases, i .e., the recompression phase (RP), the decompression phase (DP) and the underpre ssure phase (UP). And the recompression wave (RW), the decompression wave (DW) a nd the underpressure wave (UW) simulated the three phases, respectively, generat ed by the equipment designed by us. The RW test, DW test and UW test were respec tively applied to the animals. And lung injuries caused by segmented shock waves were discussed. Results: Under the experimental conditions, the RW did not caus e obvious lung injury, but the DW could cause different severities of lung injur ies. The greater the decompression ranged and the shorter the decompression dura tion was adopted, the more severe the lung injury was observed. The UW, to some extent, could cause obvious lung injury. Conclusions: It suggests that lung injury under shock waves pro bably occurs during the DP primarily. It probably does not cause direct obvious lung injury during the RP, but significantly influences the capability of causin g lung injury during the DP.
