The CardioPump permits the rescuer to actively re-expand the chest during the decompression phase of cardiopulmonary resuscitation (CPR). Active compression decompression CPR (ACD CPR) enhances the intrathoracic vacuum (negative pressure) during chest wall recoil, resulting in more blood being returned to the heart (preload). Enhanced preload lead to increased cardiac output on the subsequent chest compression.

When ACD CPR is preformed in conjunction with the ResQPOD Impedance Threshold Device (ITD), hemodynamics are further improved.


In-hospital and out-of-hospital studies* have shown that performing ACD CPR:

• Increases arterial blood pressure
• Increases coronary perfusion pressure
• Lowers intrathoracic pressure during the decompression phase of CPR
• Increases short-term and long-term survival rates
