First aid is temporary care given to an injured or ill person until medical assistance arrives. The objectives of first aid are to alleviate pain and suffering, prevent further injury, and prolong life. The basic steps of first aid are:
1. Check for responsiveness and activate emergency services.
2. Follow the ABCs - Airway, Breathing, Circulation. Ensure the airway is clear, check for breathing, and check the pulse.
3. Conduct a more thorough secondary survey checking for additional injuries, taking a medical history, and monitoring vital signs like pulse and breathing rate.
4. Continue providing care until emergency responders arrive.
