When should you call for emergency medical services (EMS)?

Calling for emergency medical services (EMS) is critical when faced with a situation involving an unconscious victim. This is because unconsciousness indicates a potentially serious medical condition that requires immediate attention. A person who is unresponsive may be experiencing issues such as a stroke, a heart attack, or a significant trauma, all of which can worsen without timely medical intervention.

In contrast, minor injuries or stable conditions may not necessitate immediate emergency response, as these can often be managed with first aid or by seeking care at a later time. Additionally, the presence or absence of visible injuries does not correlate with the need for emergency assistance; a person can be seriously ill or in danger without any external signs. Thus, understanding that unconsciousness is a clear and pressing indicator for emergency assistance is key in first aid scenarios.
