Background: The impedance threshold device (ITD) is designed to enhance venous return and cardiac output during cardiopulmonary resuscitation (CPR) by increasing the degree of negative intrathoracic pressure. A large scale trial revealed one such automatic CPR device, called the AutoPulse, increased the survival rate of patients in need of CPR by 3.6%. The non-invasive, single-use device prevents unnecessary air from entering the chest during CPR, creating a negative pressure vacuum as the chest recoils. When we talk of low-impedance headphones, the threshold of how low the impedance should be is somehow non-standardized. The increased preload to the heart helps make compressions more effective and increases the chances of a successful defibrillation and return of spontaneous circulation.
