UNLABELLED An impedance threshold valve (ITV) is a new airway adjunct for resuscitation that permits generation of a small vacuum in the chest during the recoil phase of chest compression. OBJECTIVES To explore in detail the expected magnitude and the hemodynamic mechanisms of circulatory augmentation by an ITV in Standard CPR. METHOD A 14-compartment mathematical model of the human cardiopulmonary system--upgraded to include applied chest compression force, elastic recoil of the chest wall… CONTINUE READING
