The technique of impedance plethysmography is described and its application to observation of lung volume changes in the horse at exercise is discussed. The results from horse at rest show that there is a close relationship between rate of lung volume change (flow rate) and the associated impedance changes during both inspiration and expiration. Impedance changes during exercise were related to inspiration and expiration by observation of associated respiratory sounds. Artefacts related to technical difficulties are also indicated.
本文描述了阻抗体积描记术，并讨论了其在观察运动马匹肺容积变化中的应用。对静止马匹的研究结果表明，在吸气和呼气过程中，肺容积变化率（流速）与相关的阻抗变化之间存在密切关系。通过观察相关呼吸音，发现运动过程中的阻抗变化与吸气和呼气有关。文中还指出了与技术难题相关的伪迹。
