对急性呼吸困难患者进行合理治疗,必须鉴别其究竟为心源性抑或肺源性。但仅据临床表现常难以确定。现讨论绝对呼气流速峰值(PEFR)在急性中度和严重呼吸困难患者鉴别诊断中的作用。对未经治疗的40例(均40岁以上)的41例次急性呼吸困难发作患者,均于用药前在急诊室进行PEFR测定,但对氧疗不加限制。入选患者的急性呼吸困难发作主要由充血性心衰(CHF)所致的肺水肿或慢

Reasonable treatment of patients with acute dyspnea, it must identify whether it is cardiogenic or pulmonary origin. However, clinical manifestations are often difficult to determine. We now discuss the absolute peak expiratory flow rate (PEFR) in the diagnosis of acute moderate and severe dyspnea in patients with role. Of the 41 untreated 40 patients (all over 40 years old) with acute respiratory distress episodes, PEFR was performed in the emergency department before treatment, but no limitation was imposed on oxygen therapy. Acute dyspnea episodes in selected patients are mainly caused by pulmonary edema or slow due to congestive heart failure (CHF)
