An inspiratory impedance threshold device is a valve used in cardiopulmonary resuscitation (CPR) to decrease intrathoracic pressure and improve venous return to the heart. The valve is a part of a mask or other breathing device such as an endotracheal tube, and may open at high or low pressures (called "cracking pressures") [citation needed]

The ResQPOD ® impedance threshold device (ITD) is a simple, non-invasive device that delivers intrathoracic pressure regulation (IPR) therapy during basic or advanced life support CPR to improve perfusion. The ResQPOD ITD lowers intrathoracic pressure during the recoil phase of CPR by selectively restricting unnecessary airflow into the chest.

Nov 2, 2010 · The impedance threshold device (ITD) is a pressure-sensitive valve that is attached to an endotracheal tube, supraglottic airway, or face mask. The ITD limits air entry into the lungs during the decompression phase of CPR, creating negative intrathoracic pressure and improving venous return to the heart and cardiac output during CPR.

Sep 1, 2011 · 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...

An impedance threshold device combined with an automated active compression decompression CPR device (LUCAS) improves the chances for survival in pigs in cardiac arrest. Circulation. 2008;118:S1449–S1450.

Nov 3, 2015 · The impedance threshold device (ITD) is a pressure-sensitive valve that is attached to an endotracheal tube (ETT), supraglottic airway, or face mask. The ITD limits air entry into the lungs during the decompression phase of CPR, enhancing the negative intrathoracic pressure generated during chest wall recoil, thereby improving venous return to ...

Describe what an ITD is & how it Perform works. Perform optimal optimal CPR CPR. 1 BILLION DOLLARS SPENT EVERY YEAR ON PATIENTS THAT WE DO NOT RESUSCITATE. Optimal CPR is key! Successfully defibrillated of a 14yr boy after surgery open chest in V-Fib.

Jun 18, 2007 · The Impedance Threshold Device is FDA approved for use as a hemodynamic adjunct in patients who are hypotensive. It is also designed for patients in cardiac arrest who are receiving chest compressions and periodic ventilations according to the American Heart Association Guidelines. 2 In the most recent Guidelines, it is recommended for ...

Mar 20, 2014 · Exploratory analysis showed that combined use of impedance threshold devices with active compression-decompression significantly increased the likelihood of return of spontaneous circulation (odds ratio=1.19 [1.00-1.40], p=0.045), favorable neurologic outcome (odds ratio=1.60 [1.14-2.25], p=0.006), and long-term survival (odds ratio=1.52 [1.11 ...

What is an Impedance Threshold Device (ITD)? - Also referred to as a ResQPOD - enhances the vacuum in the chest that forms during the chest recoil phase of CPR - draws more blood back to the heart (increases preload), and increases cardiac output, blood pressure, perfusion to vital organs and survival rates
