Formic acid, when combined with sulfuric acid, gets dehydrated to form carbon monoxide (CO). A 27-year-old female was found unconscious inside a car, next to a container with a mixture of sulfuric acid and formic acid. Concentrations of up to 400 parts per million of CO were measured inside the car post ventilation. Serum carboxyhemoglobin level was 15% after receiving 100% oxygen for two hours. The patient received hyperbaric oxygen therapy after which she was extubated with normal mental status. On follow-up after three months, she demonstrated neurocognitive abnormalities suggestive of delayed neurological sequelae from CO exposure.
甲酸与硫酸混合时会脱水形成一氧化碳（CO）。一名27岁女性被发现昏迷在一辆汽车内，旁边有一个装有硫酸和甲酸混合物的容器。通风后，车内测得的一氧化碳浓度高达百万分之400。在接受两小时100%氧气治疗后，血清碳氧血红蛋白水平为15%。患者接受了高压氧治疗，之后拔管，精神状态正常。三个月后的随访中，她出现了神经认知异常，提示一氧化碳暴露导致了迟发性神经后遗症。
