Importance of CPR 

• An adult collapses suddenly
• A bystander is unwilling, unable, or not sure how to perform full CPR, or is waiting for trained assistance to arrive.
• A responder does not have a breather barrier and does not want to perform unprotected rescue breaths.

• a drowning person 
• a respiratory emergency that may have caused the cardiac arrest 
• a child or baby

• Check the Scene.  Is it safe? 
• Check the Person.
• Ask the person, “are you okay?” 
• If the person does not respond to your voice, tap the person on the shoulder.
• Does the person want your help?  If someone is unconscious you can assume you have consent to give first aid.

• hand placement
• speed
• depth (at least 5cm/2")

• Depends on local funding and initiatives
• Airports
• Shopping Malls 
• Rec Centres 
• Schools 
• Good idea to be familiar with location of emergency equipment of places you frequent. 
• Usually a sign at the building entrance; large sign showing where the AED is stored 
• Some have a siren that sound if the box is opened, this is a good thing, leave the door open so others know there's an emergency 

• The machine analyzes the heart rhythm
• Looking for a rhythm that's chaotic or too fast.  In both cases the heart isn't pumping effectively
• Defibrillation sends an electrical current through the heart to stop abnormal activity and allows the heart to re-establish normal electrical impulses.  Like doing a ctrl-alt-del on your computer
• For each minute the person waits for defibrillation the chance of suvival drops 7-10%.

• Practice with the machines 
• Covers pad placement
