SpecialtyCare associates have conducted numerous research studies that have used data obtained as part of the quality improvement process. One such study, “Goal-Directed Perfusion Methodology for Determining Oxygenator Performance During Clinical Cardiopulmonary Bypass,” evaluates three oxygenators currently in clinical use and reflects how information collected by perfusionists could be utilized to provide new information to bridge gaps in knowledge when an absence of quality data is encountered.

The oxygenator study was undertaken at a hospital performing less than 200 cardiac surgical cases per year with an operative team of two perfusionists, two cardiac surgeons, two anesthesiologists, and three physician assistants. In addition, there were four operating room nurses and approximately 10 intensive care unit nurses who managed postoperative care.

The results demonstrated that newer generation oxygenators with integrated arterial filters performed better (gas transfer, postoperative transfusion rate) than an older generation oxygenator with an external arterial line filter. The data collected prospectively did not originate from a randomized clinical trial, so interpretation of the results needs to be undertaken with caution. Nevertheless, the information obtained does provide a foundation that can be used to generate future studies to further address the question.
