Summary

This study tests whether a single training session can improve police officers' ability to recognize agonal breathing — an abnormal gasping pattern that can be mistaken for normal breathing during cardiac arrest. Over 3,400 officers in New Taipei City will take a 20-minute CPR refresher and a 40-minute agonal breathing recognition course. Their knowledge and recognition accuracy will be measured before and right after the training using anonymous online questionnaires.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: CPR refresher and agonal breathing recognition training
What this could lead to: If successful, this training could help police officers better identify cardiac arrest and start CPR earlier, potentially saving more lives before emergency services arrive.
What could go wrong: This is a single-session training study with immediate post-training assessment, so long-term skill retention and real-world impact are not measured. Results may not apply to other regions or emergency responders.
