Abstract

Abstract: In order to explore correspondence between four vital signs of human body (respiratory, temperature, pulse, blood pressure) and life status of the wounded, firstly, collected data of 50 samples of the wounded were analyzed using descriptive statistics. Then, a method for rapid assessment of injury severity (RAIS) was proposed based on cluster analysis and PCA, and severity of 50 samples was graded accordingly. Finally, difference in assessment results between National Early Warning Score (NEWS) and RAIS was compared and analyzed. The results show that linear function of principal component score obtained through analysis of four vital signs can be used to assess injury severity of the wounded. The greater this score is, the more severe the injury would be. And since contribution rate of first principal component (PC1) is relatively large, PC1 score should be taken as main basis for actual injury severity assessment.

Key words: cluster analysis, principal component analysis (PCA), severity of injury, vital signs, condition assessment method
