气急鉴别指数判别呼吸困难类型的初步研究

The Study of Separation of Cardiac vs Pulmonary Dyspnea by dyspnea differentation index

目的 探讨气急鉴别指数 (dyspnea differentiation index,DDI)判别肺源性呼吸困难与心源性呼吸困难的优越性。方法 测定 116例急性呼吸困难的 Pa O2 和 PEF值 ,根据 Rajesh K.Ailani等创立的公式计算气急鉴别指数 DDI,用 DDI对 116例急性呼吸困难的原因进行判别并与 PEF和临床表现的诊断符合率相比较。结果 DDI、PEF和临床表现对 116例急性呼吸困难的原因的诊断符合率分别为 92 .7%、77.5 %、6 8.9%。结论 用 DDI判别肺源性呼吸困难与心源性呼吸困难具有较高的诊断符合率 ,明显优于

Objective To explore the advantage of dyspnea differentiation index(DDI) for separation of cardiac vs pulmonary dyspnea.Method We detected the PaO 2 and the PEF of 116 patients with acute dyspnea,then caculated the DDI by means of the formula created by Rajesh K.Ailant et al.Secondly,we differentiated the cardiac vs pulmonary dyspnea to use the DDI and compared the coincidental rate.of the diagnosis with PEF and symptoms.Results The coincidental rate of the diagnosis with DDI?PEF and the symptoms was respectively 92.7%,77.5% and 68.9%.Conclusion Because there was a higher coincidental rate of the diagnosis,so it was better to differentiate the cardiac vs pulmonary dyspnea using the DDI than PEF and symptoms.
