【摘要】 本文应用阻抗—导纳式心输出量机对40名正常成年人(男、女各半)进行每搏量(SV)的测定,并把 Sramek 公式及 Sramek 修正式和导纳法3种不同方法测得的 SV 进行比较。结果表明,应用 Stamek 公式和 Sramek修正式测得的 SV 均大于标准对照值,而导纳法的 SV 值在标准对照值范围内。提示导纳法测得的 SV 值可能更为可靠。更多还原

【Abstract】 This paper describes that we measure the stroke volume (SV) values of 40 normal people (20males,20 females)with the impedance/admittancecardiac output(CO)device,and compare the SV values measured bythe three different methods.The methods are EAP,Sramek formulaand its revised form,The result indicates that both of the SV valuesmeasured by Sramek formula and its revised form are larger than thestandard values,but the SV values measured by EAP are in the rangeof the standard values.In other words,the method of EAP is morereliable.更多还原
