Significance

• The Star of Life is the symbol of emergency medical personnel in many countries.
  
  Knowing how to save a life should be a must for everyone. Simple activities such as CPR and the Heimlich Maneuver are very effective means of assisting someone in need.
  
  

Types

• There are many types of first aid activities. Standard "patch-work" using bandages and chemical antibiotics are just the start. There are more advanced techniques such as emergency drug therapy and triage techniques for trauma cases.
  
  

Potential

• First aid activities have the potential to save a human life. Techniques are available that can keep a person alive until qualified medical personnel arrive, or that can mitigate damage caused by heart attacks and strokes.
  
  

Time Frame

• First aid should be administered as soon as it is safe to do so. Always try to administer first aid treatment quickly to help avoid long-term damage to the subject.
  
  

Warnings

• Never place your own life in danger to administer first aid treatment. If there is danger, don't risk it, especially in trauma cases, since you may cause more work for emergency personnel if you're injured in the process.
