What is the primary function of the Protek Duo cannula?

The Protek Duo cannula is specifically designed to support right ventricular failure by facilitating both right ventricular assistance and providing venous drainage for gas exchange. This dual function allows for effective management of patients who are experiencing right heart failure, particularly those who may be undergoing treatments like ECMO.

The design of the Protek Duo cannula enables it to access the right atrium for blood drainage while simultaneously delivering oxygenated blood back into the pulmonary artery. This is crucial in cases of right ventricular failure, where the heart is unable to effectively pump blood to the lungs for oxygenation. By using the Protek Duo, clinicians can maintain adequate pulmonary blood flow and improve oxygen delivery to the body, which is essential in critical care settings.

In contrast, the other options focus either on conditions or functions that do not align with the primary role of the Protek Duo. While it may influence aspects of pulmonary edema or assist with left ventricular failure indirectly, the primary indication and function of this device is to directly support the right ventricle.
