目的 通過(guò)無(wú)創(chuàng)的微血管血液黏度與低切血液黏度之間的相關(guān)性，探究基于指脈的血液黏度無(wú)創(chuàng)檢測(cè)的可行性。 方法 首先采集被測(cè)者的靜脈血、指尖光電容積脈搏波及生理信息；然后使用指脈波形面積擬合微血管半徑，通過(guò)泊肅葉定律公式計(jì)算無(wú)創(chuàng)的微血管血液黏度；最后用SPSS軟件分析微血管血液黏度計(jì)算值與全血黏度的相關(guān)性以及血液黏度與基礎(chǔ)生理因素、血液生化因素之間的相關(guān)性。 結(jié)果 微血管血液黏度計(jì)算值與低切血液黏度呈正相關(guān)。體重、腰圍、體表面積、總膽固醇與微血管血液黏度計(jì)算值、低切血液黏度呈正相關(guān)；高密度脂蛋白與微血管血液黏度計(jì)算值、低切血液黏度呈負(fù)相關(guān)。結(jié)論 通過(guò)指脈無(wú)創(chuàng)檢測(cè)出來(lái)的微血管血液黏度，與有創(chuàng)檢測(cè)出來(lái)的低切血液黏度之間的正相關(guān)性以及二者狀態(tài)變化規(guī)律的一致性表明，基于指脈的血液黏度無(wú)創(chuàng)檢測(cè)具有一定的可行性。
