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.
