What is considered the immediate care given until medical assistance arrives?

First aid refers to the immediate and initial care provided to an individual who has sustained an injury or is experiencing a medical emergency. This care is crucial because it can stabilize the person's condition, alleviate pain, and prevent further harm until professional medical help arrives. First aid techniques may include assessing the situation, performing CPR, controlling bleeding, or treating for shock among other life-saving actions.

In the context of flight attendants and emergency situations, the training ensures that crew members can perform essential first aid to manage emergencies on board, enhancing passenger safety significantly. First aid can be administered by individuals without advanced medical training; it focuses on providing necessary care while waiting for a more qualified medical professional to take over.

Other options like emergency evacuation, rescue breathing, and medical transport, while essential in certain contexts, do not encapsulate the concept of the immediate care provided until professional help arrives, which is the core idea of first aid.
