You should call 999 in a medical emergency. This is when someone is seriously ill or injured and their life is at risk.
Medical emergencies can include:
- loss of consciousness
- an acute confused state
- fits that aren't stopping
- chest pain
- breathing difficulties
- severe bleeding that can't be stopped
- severe allergic reactions
- severe burns or scalds.
You should call 999 immediately if you or someone else is having a heart attack or stroke. Also call 999 if you think someone has been involved in a major trauma, for instance a road traffic accident, a stabbing or a fall from height.
