True or False: Cardiotomy reservoirs are extremely effective at defoaming the extraordinary amount of emboli developed during intracardiac and intraperitoneal suctioning.

Cardiotomy reservoirs play a critical role in heart surgery by collecting blood that is suctioned from the surgical site. While they do have some ability to separate air from blood and can help reduce the amount of foam generated during suctioning, they are not extremely effective at completely defoaming or removing all of the emboli produced.

The primary function of cardiotomy reservoirs is to collect and filter blood for re-infusion. They facilitate some degree of defoaming, particularly with the use of a defoaming agent or through the design of the reservoir itself, which can trap bubbles to some extent. However, if the volume of bubbles or emboli is excessive, the reservoirs may not effectively manage the situation, leading to potential complications.

In practice, the effectiveness of a cardiotomy reservoir in removing emboli can vary based on factors such as the surgical technique, the specific design and features of the reservoir, and the presence or absence of additional filtration devices. Therefore, stating that they are extremely effective at this task is not accurate, which validates the assertion that the statement is false.
