T​he ResQPOD is an impedance threshold device (ITD) that provides Intrathoracic Pressure Regulation (IPR) Therapy to maximize vital organ blood flow and provide perfusion on demand during cardiac arrest. By selectively preventing unnecessary air from entering the chest during chest wall recoil, the ResQPOD enhances the vacuum in the chest that increases preload and lowers intracranial pressure; as a result, more blood is circulated to vital organs. The goal of this course is to provide you with essential information about how an ITD works, and how it is used during CPR to enhance blood flow.
