Vicarious audiovisual learning in perfusion education.

Area of Science:

• Cardiovascular Technology
• Medical Simulation
• Perfusion Education

Background:

• Traditional perfusion training relies on didactic methods and clinical experience.
• Patient safety concerns limit opportunities for students to practice complex scenarios or equipment setup.
• High-fidelity simulators offer advanced training but can be costly.

Purpose of the Study:

• To compare the efficacy of vicarious audiovisual learning versus text-based learning for perfusion education.
• To assess the impact of low-fidelity simulation on student cognition and knowledge retention.
• To evaluate student satisfaction with different online learning module formats.

Main Methods:

• Thirty-seven perfusion students were randomized into two online learning groups: text-based or video-based.
• Modules focused on the setup and operation of the MAQUET ROTAFLOW centrifugal pump.
• Cognitive assessment used 10-question multiple-choice tests administered immediately post-module and two weeks later.

Main Results:

• Video learners achieved significantly higher scores on both immediate (88.89% vs 74.74%) and delayed (77% vs 60%) testing compared to text learners.
• Video learners reported higher satisfaction with their learning experience.
• Survey data indicated a preference for audiovisual learning among contemporary perfusion students.

Conclusions:

• Vicarious audiovisual learning presents an effective and economical method for perfusion training, particularly for equipment operation.
• Video-based modules appear to enhance learning, cognition, and retention of perfusion concepts.
• Audiovisual simulation holds promise for the future of perfusion education alongside advancing simulation technologies.
