Carbon monoxide (CO) is responsible for more poisoning fatalities each year than any other toxic agent. The often insidious nature of the symptom progression and its ability to imitate many common illnesses may result in the failure to diagnose a potentially fatal outcome. CO detectors equipped with an audible alarm can alert potential victims of CO poisoning before toxic sequelae develop. A study was conducted in which all calls to 911 concerning a CO detector in alarm or regarding possible CO poisoning were investigated by a paramedic crew; 101 possible CO exposures were investigated. CO detectors with audible alarms were the genesis of 59.4% of the calls. Detectable CO levels were found in 69.3% of the investigations, and 80% of the homes with detectors had verifiable CO concentrations. The mean CO concentration in homes with detectors was 18.6 ppm, compared with 96.6 ppm when no detector was available; 63.4% of the victims with no alarm were symptomatic, compared with 13.3% of victims with alarms. CO detectors with audible alarms were effective in alerting the potential victims of CO poisoning to its presence. Persons with CO detectors were less likely to become symptomatic from a CO exposure than those who did not have CO detectors.
每年，一氧化碳（CO）导致的中毒死亡人数比其他任何有毒物质都要多。症状进展往往具有隐匿性，且它能够模仿许多常见疾病，这可能导致无法诊断出潜在的致命后果。配备可听警报器的一氧化碳探测器能够在中毒后遗症出现之前，提醒潜在的一氧化碳中毒受害者。一项研究对所有拨打911报告一氧化碳探测器报警或可能一氧化碳中毒的电话进行了调查，护理人员对101起可能的一氧化碳暴露事件进行了调查。带有可听警报器的一氧化碳探测器是59.4%的报警电话的起因。在69.3%的调查中发现了可检测到的一氧化碳水平，并且80%装有探测器的家庭中一氧化碳浓度得到了证实。装有探测器的家庭中一氧化碳的平均浓度为18.6 ppm，而没有探测器时为96.6 ppm；没有警报器的受害者中有63.4%出现了症状，而有警报器的受害者中这一比例为13.3%。带有可听警报器的一氧化碳探测器能够有效地提醒潜在的一氧化碳中毒受害者其存在。与没有一氧化碳探测器的人相比，拥有一氧化碳探测器的人因接触一氧化碳而出现症状的可能性更小。
