Thoracocardiography approach pretends to non-invasively monitor stroke volume by inductive plethysmographic recording of ventricular volume curves by a transducer placed on the chest. The purpose of this study was to investigate the potential of thoracocardiography to estimate stroke volumes while apnea with open glottis. We hypothesized that, when glottis is open, stroke volumes would be better estimated if airways flow curves were taken into account.
胸廓心动描记法试图通过放置在胸部的传感器对心室容积曲线进行感应式体积描记记录，以无创方式监测每搏输出量。本研究的目的是探讨胸廓心动描记法在声门开放时呼吸暂停期间估计每搏输出量的潜力。我们假设，当声门开放时，如果考虑气道流量曲线，每搏输出量将能得到更好的估计。
