L'estimation du volume d'éjection par la thoracocardiographie est meilleure quand la glotte est fermée

Thoracocardiography approach pretends to noninvasively 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.
