The poor outcomes of this disease process are caused by the delay in initiating therapy because of the difficulties in making an accurate and timely diagnosis. In this study, we tried to conduct patterns analysis on blood pressure (BP) signal under simulated situation using an innovative measurement of similarity. The simulations of intestinal artery occlusion were conducted to two young healthy pigs to generate the recordings of blood pressure signals in dynamically transitional situation. Based on the distance measurement of similarity, non-clamping, non-relaxing, and blocking indexes are defined. Moreover, blocking index (BI) performs a good indicator for verifying the pattern of BP signal under the situation of clamping or relaxing. Finally, the analysis results show the feasibility of pattern analysis for identifying the underlying condition of circularity system.Keywords:Arterial occlusionBlood pressureSimilarityNon-clamping indexNon-relaxing indexBlocking index References L.
