Which device is minimally required to provide feedback about compression rate during CPR practice?

The requirement for minimal feedback during CPR practice focuses on providing a consistent measure of compression rate, which is crucial for effective chest compressions. A metronome serves as an auditory guide, producing a steady beat that helps instructors and participants maintain the recommended compression rate of 100-120 compressions per minute.

Using a metronome is beneficial because it provides a clear and consistent cadence for compressions, allowing learners to synchronize their actions and ensuring that they are performing compressions at the correct pace. This auditory feedback is vital, especially for beginners, to learn the rhythm and proper timing needed for effective CPR delivery.

While other options may offer some form of feedback, they do not provide the same level of auditory pacing critical for mastering compression rates. For instance, a lighted manikin may give visual feedback, but it doesn't ensure that the appropriate compression rate is being achieved. Similarly, student counting can be inconsistent and may not align with the recommended rate. A manikin with a timing beep can provide feedback but may not be universally available or as effective in emphasizing the need for rhythm and consistency during compression.
