With the increasing expectancy on quality of life of patients, reconstruction surgery is widely performed. Tissue circulation monitoring plays an important role in early detection of compromised circulation after surgery. However, conventional approaches were not continuous, and conventional tissue circulation judging algorithm did not evaluate the influence of continuous motion noise artifact. In this study, the algorithm that we developed for judging normal circulation, compromised circulation and artifact were evaluated in continuous monitoring situation. Nine healthy volunteers attached our probe on abdomen or chest continuously for four to seven days. The algorithm was evaluated by usage of data and specificity calculated from data of eight volunteers (one female, seven males, one quit). Result showed that for eight healthy volunteers, the algorithm continuously obtained intensity data, and the usage of data at night and specificity of one-week monitoring were 89.7 ± 3.0 % and 99.3 ± 0.6 % respectively. This study indicates that our algorithm is feasible in continuous tissue circulation monitoring.
