A medical emergency is a situation in which immediate medical attention is required to prevent serious harm or death.

The A&E (Accident and Emergency) department is a specialized department in a hospital that provides immediate medical care to patients with acute injuries or illnesses.

First aid procedures are the initial steps taken to provide medical assistance to someone in need before professional medical help arrives.

Sudden cardiac arrest is a life-threatening emergency in which the heart suddenly stops beating, leading to a loss of blood flow to the brain and other vital organs.

The triage method is a system used in emergency departments to prioritize patients based on the severity of their condition, ensuring that those in critical condition receive immediate attention.
