When treating cardiorespiratory arrest on the battlefield, the Advanced Circulatory® ResQPOD® Impedance Threshold Device regulates pressure in the thorax and prevents unnecessary air from entering the chest during CPR, creating a vacuum that pulls more blood back into the heart, resulting in better casualty outcomes.

The ResQPOD®, part of Combat Medical Systems’ MARCHMedical Gear, enhances circulation during basic or advanced life support CPR. This simple non-invasive device regulates pressure in the chest, improves blood flow to the heart and brain, and provides Perfusion on Demand (POD). In clinical studies, use of the ResQPOD® increased blood flow to the brain by 50%3 and blood flow to the heart by 100%.2 ResQPOD® has also demonstrated an increase in neurologically intact survival of 25% or more.1

Timing lights guide proper compression and ventilation rates, promoting high-quality CPR. ResQPOD® helps circulate drugs more effectively and does not restrict patient ventilation or exhalation.
