AVL945型血气分析仪,是瑞士 AVL 公司最近几年推出的一种新型血气分析仪。它利用微机控制,使全部工作自动化,从而减少了操作人员带来的误差。该机通过高精度的微型电极可测定出全血样本中的酸碱度值(pH)、二氧化碳分压(PCO_2)和氧分压(PO_2),并根据内设装置所测得的大气压值以及病人的温度和血红蛋白(Hb)的含量和类型(成人/儿童/P5)等输入参数,计算出另外九个参数:剩余碱(BE)、细胞外液剩余碱(BE_(ECF))、血液缓冲碱(BB),血浆实际碳酸氢根浓度(HCO_3~-)、血浆二氧化碳总量(TCO_2),标准碳酸氢根浓度(SBC)
AVL945 blood gas analyzer, is the Swiss AVL company launched a new blood gas analyzer in recent years. It uses microcomputer control, all the work automation, thereby reducing the operator error. The machine can determine the pH value, the partial pressure of carbon dioxide (PCO_2) and the partial pressure of oxygen (PO2) in the whole blood sample by using the high-precision microelectrode, and according to the atmospheric pressure measured by the built-in device and the patient’s Temperature and hemoglobin (Hb) content and type (adult / child / P5) and other input parameters to calculate the other nine parameters: residual base (BE), extracellular residual base (BE ECF), blood buffer base BB), actual plasma bicarbonate concentration (HCO 3 -), total plasma carbon dioxide (TCO 2), standard bicarbonate concentration (SBC)
