If someone on the field of play has an unexpected collapse and remains unresponsive, e.g. does not sit up or appear to move purposefully, does not interact with those around them, does not respond to being spoken to or touched, it should be assumed that they have had a cardiac arrest unless proven otherwise.
The collapsed person may not be breathing at all or may not be breathing normally. In the early stages following cardiac arrest, there may be slow, laboured breathing and/or short episodes of seizure-like movements, and their eyes may be open. Sometimes people who have had a cardiac arrest may pant or continue to breathe more rapidly. This should not delay the recognition of cardiac arrest.
If anyone collapses during a sporting activity and remains unresponsive, treat this as a cardiac arrest.
An unexpected collapse may occur at any time during sporting activity:
- In the warm-up, training or practice, in competition and during the post-activity recovery period.
- Immediately after blunt-force trauma to the chest, or through collision with another athlete’s elbow or knee, sporting equipment, or through a ball hitting the chest.
Anyone who sees an unexpected collapse should call for help immediately. Even if the person recovers and regains consciousness quickly, they should receive prompt medical attention. They should not continue in their sporting activity. They should leave the field of play and seek immediate medical attention.
Immediate steps to take
If an individual is having a suspected cardiac arrest following an unexpected collapse, it is vital to take the following steps to ensure the best chance of survival:
- Check: Is it safe to approach? If the person suddenly collapses and is unresponsive, presume this is a cardiac arrest until proven otherwise.
- Call for help: Call for an ambulance (999) on speakerphone and tell the operator “cardiac arrest” and provide as many details as possible, including the location (e.g. What3Words), the nature of the emergency, and that an AED is needed. Initiate the call first, then assess breathing while waiting for the call to be answered. The ambulance service call handler will be able to assist you in identifying abnormal breathing, if needed.
- CPR: Begin chest compressions immediately and start high-quality chest compressions (CPR) without delay. If you have been trained to provide rescue breaths, alternate 30 chest compressions with 2 rescue breaths.
- Attach and switch on an AED immediately: Send someone to fetch and attach the AED as soon as it arrives. Follow the AED voice instructions. An AED should be located at sports venues and training grounds so that a first shock, if appropriate, can be delivered within two minutes of the athlete’s collapse.
- Continue until help arrives: Continue doing effective CPR and defibrillation until the ambulance service arrives and takes over, as this will give the individual the greatest chance of survival.
AEDs can be used on children and adolescents who have a cardiac arrest. Some AEDs have a separate mode for children under 25 kg (approximately eight years of age), but if it does not, use it in its standard adult mode.
