在无创测量及监视生理活动的研究方法中,电阴抗技术的应用重新受到重视。目前,在呼吸系统中,此项技术的应用局限于对新生儿窒息及胸腔积液变化的监测。在实验室和临床中,身体活动受到限制或不明显的情况下,可使用阻抗法间接地监测呼吸量。但买际上别的一些方法用得更为普遍。因为它们不仅也是无创的,而且能直接确定呼吸量。属于后一种类的仪器有肺活量计和呼吸速度测定器。这些仪器的明显缺陷是需要插入气 In non-invasive measurement and monitoring of physiological activity research methods, the application of electroneurology anti-technology re-attention. Currently, in the respiratory system, the application of this technique is limited to the monitoring of changes in neonatal asphyxia and pleural effusion. Impedance measurements may be used to monitor respiration indirectly, in both laboratory and clinical settings where physical activity is limited or insignificant. However, some of the other methods of buying are more common. Because they are not only non-invasive, but also determine the amount of breath directly. The latter category has spirometers and respiration rate testers. The obvious flaw with these instruments is the need to insert gas
