When should an emergency medical service be called during a first aid situation?

Calling emergency medical services (EMS) is crucial in situations where someone’s life is at risk. When a situation is life-threatening, such as severe bleeding, difficulty breathing, signs of a heart attack, or any other critical health issue, immediate professional help is vital. The faster EMS arrives, the better the chances of survival and recovery for the victim.

It's important to act swiftly because delays can lead to worsened conditions or irreversible damage. In contrast, waiting for the victim to request aid, for a first aid provider to tire, or after conducting tests could lead to dangerous consequences or exacerbate the victim's condition. Promptly involving EMS ensures that trained professionals can provide the necessary medical care as quickly as possible.
