Importance of Conclusion
More objective feedback on compression performance during CPR courses is needed; instructor judgment alone is insufficient. Both human examiners and learners would benefit from measurement and feedback on compression performance during CPR courses.
- Learner competency of CPR skills during layperson CPR training depends entirely on judgments made by an instructor; research suggests these judgments are not precise or accurate.
- Results of this study included inadequate compression depth rated as adequate 55% of the time, and incorrect hand placement rated adequate 49% of the time.
- Study results show instructors do not always detect poor compression performance; hence some individuals with inadequate skills still receive instructor approval.
- This study cites research that shows a large disparity between manikin and human measures of chest compressions and ventilations.
