Which of the following is a desirable technology feature in CPR training manikins?

A built-in feedback device is considered a desirable technology feature in CPR training manikins because it enhances the learning experience by providing real-time feedback to the trainees. This feedback can include metrics such as compression depth, rate, and chest recoil, allowing learners to understand and correct their performance immediately. The ability to assess their technique helps reinforce proper CPR skills, leading to improved retention of the material and greater confidence in real-life situations where someone may need to perform CPR.

In contrast, while an inflatable design might provide portability, it doesn’t necessarily enhance the quality of training. High-cost performance, while an important consideration in many purchasing decisions, does not directly contribute to the effectiveness of the training experience itself. Basic functionality, on the other hand, may limit the depth of learning, as it would lack the advanced feedback mechanisms critical for skill development. Thus, the built-in feedback feature is key in fostering effective learning and skill mastery in CPR training.
