In cardiopulmonary bypass and extracorporeal life support, oxygenators must deliver efficient gas exchange while maintaining stable blood flow. One critical performance parameter is pressure drop — the resistance the device imposes on circulating blood. Excessive pressure drop can strain the pump, destabilize perfusion, and increase risks of hemolysis or clot formation. That’s why ISO 7199 and FDA Guidance for Cardiopulmonary Bypass Oxygenators require rigorous pressure drop testing as part of device validation.
At our laboratory, we conduct Pressure Drop testing in full compliance with ISO 7199 and FDA Guidance, ensuring every oxygenator is evaluated under clinically relevant operating conditions.
