The results show that increasing the area of the smoke outlet will reduce the thickness of the smoke layer;The top smoke outlet can effectively reduce the temperature at the smoke outlet, and the temperature at the downstream of the smoke outlet is obviously lower than the temperature at the upstream of the smoke outlet;The bend in UTLT can delay the longitudinal spread of smoke. Changing the distance between the fire source and the smoke outlet has little effect on the one-sided centralized smoke exhaust.展开更多

Methods: 80 traumatic shock patients in our hospital from January 2019 to June 2020 were divided in two groups. The control group was given routine care, and the experimental group implemented the operating room rescue nursing cooperation. The success rate of rescue and complication rate were compared between the two groups. Results: the success rate of rescue and the complication rate was lower than the control group, P <0.05. Conclusion: the effect of traumatic shock patients can improve rescue success rate and reduce complication rate.展开更多
