一氧化碳(CO)中毒是最常见的工业中毒之一。接触CO或中毒时,血中COHb增高,使血液失去携氧能力。血中CO饱和率是与心输出量成正比,因而活动者比坐着或休息时会更快地发生CO中毒。 很多研究证明COHb的形成不是CO毒性的主要机理。动物实验证明COHb的浓度在CO中毒中只有较小和次要的作用。另一些研 Carbon monoxide (CO) poisoning is one of the most common industrial poisonings. Exposure to CO or poisoning, the blood COHb increased, the blood loss of oxygen carrying capacity. Saturation in blood CO is proportional to cardiac output, so activators CO poisoning occurs more rapidly than sitting or resting. Many studies have shown that the formation of COHb is not the main mechanism of CO toxicity. Animal experiments show that COHb concentrations have only minor and secondary effects in CO poisoning.
