血气比色分析法是根据氧合血红蛋白和还原血红蛋白对一定波长光波吸收率不同和急性呼吸衰竭时动脉血二氧化碳分压(PaCO_2)与pH相关的原理,探索该法在急性呼吸衰竭实验中的应用。 一、方法 家兔20只,按常规方法复制窒息、气胸及肺水肿模型。按心导管检查时取血方法抽取兔正常动脉血6 ml和窒息、气胸、肺水肿时动脉血各3 ml, Blood gas colorimetric method is based on the principle that oxygenated hemoglobin and reduced hemoglobin have different absorption rate of light wave at a certain wavelength and arterial carbon dioxide partial pressure (PaCO_2) and pH at acute respiratory failure, and explores the application of this method in acute respiratory failure experiment . First, the method 20 rabbits, according to the conventional method of copying asphyxia, pneumothorax and pulmonary edema model. According to the method of taking the catheter when the blood sampling rabbit normal arterial blood 6 ml and asphyxia, pneumothorax, pulmonary edema, arterial blood 3 ml each,
