AVL-995Hb血气分析仪是瑞士生理医学仪器公司生产的全自动血液酸碱平衡及血气分析仪，同时测量血液PH、二氧化碳分压、氧分压和血红蛋白，根据上述四项参数结合仪器测出的当地的大气压值，输入病人的体温和吸氧浓度计算出其余11项参数。AVL使用纯净的二氧化碳和干燥的压缩空气?
AVL-995Hb blood gas analyzer is a fully automatic blood acid-base balance and blood gas analyzer produced by Swiss Physiotherapeutic Instrument Company. It also measures the blood PH, carbon dioxide partial pressure, oxygen partial pressure, and hemoglobin. It is measured according to the above four parameters combined with the instrument. For the local atmospheric pressure, enter the patient’s body temperature and oxygen concentration to calculate the remaining 11 parameters. Does AVL use pure carbon dioxide and dry compressed air?
