辦公室的工作者常常因為長時間久坐在固定的位置上，容易忽略血液循環不良所帶來的後果。為了能夠評估循環不良所造成的影響程度，本系統結合多個生理參數來分析，以便達到更好的效果。首先會從光體積描繪中找到動、靜脈的順應性，這可以知道血管的拉扯程度，以及在組織中所佔有的血量多寡。利用心電圖去分析找出心率變異，從中找到交感、副交感神經之間的作用強度，這可以知道靜脈回流的機制是否被驅動。從心電圖和光體積描繪參數整合中去找出脈波傳導速度，用以評估血管的緊繃程度。把人體的呼吸做頻譜分析用來評估出交感、副交感神經之間的平衡關係。再將收集到的血流光反射訊號做諧波分析，找出各經絡的能量，這點可以反應出經絡的缺氧程度。透過分析5 種生理參數，來比較久坐之後使用腹式呼吸及慢走的方式來改善生理狀況的差異性。

Workers in the office often sit in the regular position for a long time. It isapt to neglect the bad consequences brought by blood circulation. In order to evaluate the bad influence caused by circulation more effectively, this system combines several physiological parameters. At first, we can find the compliances of artery and vein from PPG measurement and this will let us know the degree and the number of blood amount occupied in organizing of blood vessel. Second, HRV can be found and analyzed based on ECG analysisto study the functioning intensity of sympathetic and parasympathetic nervous systems. This will also be used to know whether the vein backset current is urged. To find out the pulse wave velocity by combining the ECG and PPG,we can evaluate the tight degree of the blood vessel. By making the spectral analysis of the breath, we can use it to evaluate the balance between sympathetic and parasympathetic nervous systems. Through harmonic analysis, we can roughly evaluate the energy distribution and oxygen shortage of each meridian. Finally, we can compare the effects of abdominal breathing and jogging to improve the related physiological conditions after sitting for a long more time,through analyzing five physiological parameters.
