Impedance Threshold Devices (ITD) have been given a Class IIa recommendation by the American Heart Association (AHA) in its recently released guidelines for CPR. IDT’s are designed to aid rescuers in enhancing circulation for patients receiving assisted ventilation during CPR.

IDT’s, such as ResQPOD®, utilizes the interdependence of the respiratory and circulatory systems to create a negative pressure within the thorax during the release phase of CPR. This increase in negative pressure results in drawing more blood into the chest and increasing venous return to the heart. The improved blood return to the heart improves cardiac output on the subsequent compression.
