    【摘要】 目的：探讨急诊床旁超声在急性呼吸困难快速鉴别诊断的价值。方法：将2020年4-9月江门市新会区人民医院急诊科接收的急性呼吸困难患者72例作为对照组，2020年10月-2021年4月江门市新会区人民医院接收的急性呼吸困难患者79例作为研究组。对照组行常规检查，研究组行急诊床旁超声检查。比较两组检查时间、急性呼吸困难病因诊断准确率及入院后不同时间的氧合指数(OI)。结果：研究组检查时间短于对照组(P<0.05)。两组重症肺炎、肺水肿、肺栓塞、COPD、气胸、胸腔积液各病因诊断准确率及整体诊断准确率比较，差异均无统计学意义(P>0.05)。研究组入院1、2 h的OI均高于对照组(P<0.05)。结论：急诊床旁超声在急性呼吸困难病因鉴别诊断中，可缩短检查耗时，快速查明病因，迅速纠正氧合状况。
