不少人对碳氧血红蛋白(COHb)在循环血液中的解离速度感兴趣。关于吸氧条件下的COHb半解离期,已有不少资料,但报告的数值,从30到80分钟不等。我们在研究一氧化碳(CO)中毒的急救措施时于1982年做了一次调查,现摘要报告于下。一、对象天津医学院附属医院就诊CO中毒患者,估计其COHb浓度较高且有可能在抢救中采取血样的,选为测试对象,共得26人。二、方法 1、给患者采血后立即给纯氧,吸氧中再采血1—2次。测其COHb浓度(％)。采血间隔长短不一,视抢救情况而定。由浓度的改变和间隔时间按半衰期公式计算半解离时间(half
Many people are interested in the rate of dissociation of carboxyhemoglobin (COHb) in circulating blood. There are a lot of information on the COHb dissociation period under oxygen conditions, but the reported values range from 30 to 80 minutes. We conducted a survey in 1982 on first aid measures for carbon monoxide (CO) poisoning and are summarized below. First, the object Tianjin Medical College Hospital attending CO poisoning patients, it is estimated that the higher concentration of COHb and may take blood samples during the rescue, selected as the test object, a total of 26 people. Second, the method 1, to the patient immediately after blood collection to pure oxygen, oxygen absorption in the blood 1-2 times. Measured COHb concentration (%). Blood collection interval varies, depending on the situation may be. The half dissociation time is calculated from the half - life equation by the change of concentration and interval time
