But how does it work? During CPR, the Impedance Threshold Device, called the ResQPOD, restricts unwanted airflow back into the lungs as the chest recoils. This allows the negative pressure begin created in the thoracic cavity to act on the circulatory system and pull more blood into the heart! As a result, systolic pressures increase and push more blood to the brain and vital organs. With more oxygen rich blood in the heart and perfusion occurring in the vital organs, the chances of successful defibrillation increases!
Animal and clinical studies have clearly shown that, during cardiac arrest, the ResQPOD combined with high-quality CPR:
- Increases blood flow to the heart
- Increases cardiac output
- Increases systolic blood pressure
- Increases blood flow to the brain
