Carbon monoxide (CO) is a major and ubiquitous component of fire atmospheres produced when organic matter is burned in an inadequate supply of oxygen. Accidental poisoning by CO is common in cold climates where fireplaces, a gas, electric or kerosene heaters or grills are used inside ill-ventilated buildings. In the Brazilian Amazon, with its hot and humid climate, there is no need for the use of heaters and accidents may occur in cases of residential fires or burning of the forests for land use in agriculture.
We present a case of CO suicide of twenty-six-year-old men.
A forensic autopsy was performed to evaluate the circumstances, cause and medio-legal death etiology.
Autopsy evidenced the typical but also not commonly published cherry-red color of the hypostasis, lungs and other organs, and the very fluid cherry-red blood. The cause of death was due to a massive CO inhalation.
While these poisonings are well recognized, and a vast number of publications on CO toxicity exist, both in an environmental and industrial context, suicide is infrequently encountered in forensic practice and the typical signs are rarely seen in the literature.
一氧化碳（CO）是在氧气供应不足时有机物燃烧所产生的火灾烟雾中的一种主要且普遍存在的成分。在寒冷气候地区，通风不良的建筑物内使用壁炉、燃气、电或煤油取暖器或烤架时，一氧化碳意外中毒很常见。在气候炎热潮湿的巴西亚马逊地区，无需使用取暖器，而住宅火灾或为农业用途焚烧森林时可能会发生一氧化碳中毒事故。
我们报告一例26岁男性一氧化碳自杀案例。
进行法医尸检以评估事件情况、死因及法医学死亡病因。
尸检发现尸斑、肺部和其他器官呈现典型的樱桃红色，这种情况虽典型但在文献中并不常见，且血液呈流动性樱桃红色。死因是大量吸入一氧化碳。
虽然这些中毒情况广为人知，并且在环境和工业领域有大量关于一氧化碳毒性的出版物，但在法医实践中，一氧化碳自杀很少见，典型体征在文献中也很少见。
