This clinical policy focuses on critical issues concerning the management of adult patients presenting to the emergency department (ED) with acute symptomatic carbon monoxide (CO) poisoning. The subcommittee reviewed the medical literature relevant to the questions posed. The critical questions are: Should hyperbaric oxygen (HBO(2)) therapy be used for the treatment of patients with acute CO poisoning; and Can clinical or laboratory criteria identify CO-poisoned patients who are most or least likely to benefit from this therapy? Recommendations are provided on the basis of the strength of evidence of the literature. Level A recommendations represent patient management principles that reflect a high degree of clinical certainty; Level B recommendations represent patient management principles that reflect moderate clinical certainty; and Level C recommendations represent other patient management strategies that are based on preliminary, inconclusive, or conflicting evidence, or based on committee consensus. This clinical policy is intended for physicians working in hospital-based EDs.
本临床政策聚焦于成年急性症状性一氧化碳（CO）中毒患者到急诊科（ED）就诊时的管理关键问题。小组委员会审查了与所提问题相关的医学文献。关键问题为：高压氧（HBO₂）疗法是否应用于急性CO中毒患者的治疗；以及临床或实验室标准能否识别出最有可能或最不可能从此疗法中获益的CO中毒患者？根据文献证据的力度给出了相应建议。A级建议代表反映高度临床确定性的患者管理原则；B级建议代表反映中度临床确定性的患者管理原则；C级建议代表基于初步、不确定或相互矛盾的证据或基于委员会共识的其他患者管理策略。本临床政策适用于在医院急诊科工作的医生。
