Recognise · At once
- Non-contact collapse = sudden cardiac arrest. Enter at once — do not wait for the ball to go out of play.
- Unresponsive to voice or touch. Gasping, slow breathing or slow seizure-like movements are cardiac arrest, not a fit.
- Red checks for signs of life: breathing and carotid pulse together, no more than 10 seconds.
- Black ensures the ambulance is called.
