Both should identify themselves as being trained First responder starts CPR while the second calls 911 or emergency number, obtains an AED, and redies AED for use.

What accounts for about 1/2 of all cardiovascular-disease-related deaths in adult Americans each year?

CHD

Should you allow AED pads to contact a metal surface?

no

Should you ever do more than 2 rescue breaths in a row?

no

If you are alone, after you perform 5 sets. If someone is with you, as soon as you know they are unconscious.

What should you do when you give CPR and rescue breaths aren't making the chest rise?

Retilt head and ensure mouth and nose are sealed correctly. If 2nd breath doesn't go in, immediately stant chest compressins. do 30 chest compressions look for object in the victim's mouth, if you see it, do a finger sweep to get the object out. If you don't see it, give 2 rescue breaths. Give 30 chest compressions, and repeat until the object is out of the airway.

What should you do to give CPR to a person who has a tracheostomy or stoma?

USe a mouth-to-stoma breathing instead. Remove anything covering the stoma. Wipe away any secretions from the stoma and make a complete seal over the person's stoma or tracheostomy tube with your mouth and blow in for 1 second to make the chest rise. If it doesn't rise, the tracheostomy tube may be blocked. Remove the inner tube and try rescue breaths again. If you hear or feel air escaping from the person's mouth or nose, the person is a partial neck breather. Seal the person's mouth and nose with your hand or a tight fitting mask so the air doesn't escape out of the mouth or nose when you give rescue breaths into the stoma.

What should you do if you can't form a tight seal over the person's mouth?

Use mouth-to-breathing instead. With the person's head tilted back, close the person's mouth by pushing on the person's chin. Make a complete seal over the person's nose with your mouth and blow in for 1 second to make the chest rise.

You should do it when you can/aren't willing to give full CPR. Give continuous chest compressions at a rate of 100-120 per minute until EMS arrives.

Atherosclerosis

a condition in which deposits of plaque, including cholesterol build up on the inner walls of the arteries, causing them to harden and narrow, reducing the amount of blood that can flow through; develops gradually and can go undetected for many years
