CPR

Infant, Child, Adult CPR all the same cycle/rate; 30 compressions, 2 breaths.

cpr cannot be done

In an unconscious victim you perform CPR the same for an obstructed airway as you would for regular CPR with one exception, before attempting ventilation you should look for the object in the mouth and if you see it, remove it. But never perform a blind finger sweep!

It's like a reset button; hopefully it will reset to the correct beating pattern.

Circulation

Yes.

There are millions; but since no one agency records this data, the exact number is not available.

Basically,

(We'll assume that you just found some dude lying unconscious on the group or something.)

1. Find victim, check surroundings for safety (downed power lines, car on fire with gas spilling out).2. Check if the person is conscious. (Try to wake them up. If they don't, contact emergency services.)

3. Check for breathing, pulse. (If not breathing, check for obstructed airway and clear if necessary.)

If you finished up with step 3 and you've concluded that they're not breathing and have no pulse, then the person is pretty much "dead".

This is when you do CPR. You do CPR to keep a flow of oxygen to the brain when the heart fails to pump on its own.

Rocker, bouncer, bender, double crosser, massager and jerker are to be avoided in the execution of cardiac compression for in minimizes the depth and efficiency of the CPR.

You want to be in the middle of the chest, because that's where the heart is (we say the heart is on the "left side", but what that really means is that there's slightly more of it on the left than on the right). Finding the tip of the sternum ensures that you're in approximately the right place, and moving up from that slightly ensures that you are compressing the heart, not pushing the xiphoid process into the liver. Xiphoid is greek for "swordlike", and the pointy tip of the sternum could easily puncture the liver if you were to really push down hard on it.

CPR is CardioPulmonary Resuscitation. Cardio means "heart". Pulmonary means "breathing". Resuscitation means "revival". When performing CPR, one works to revive a person by activating the heart and lungs.

Child CPR is given to children ages 1 to 8 years old.

The most critical is call 911 (or if you are in a hospital or care facility, follow your protocols). You aren't going to save them alone. Next would be deep rapid compressions. Keep that blood moving and oxygen to the brain. There are many aspects to CPR that are critical, these are the most critical in my opinion.

Edit: As always, keep yourself safe. That should be first. :)

Yes, if they need it!

If they get to the point where you've found them unresponsive, not breathing and with no signs of life...

You've called EMS (and for an AED) or had someone else do it....

And nothing's happened (no apparent recovery)

Then it's time to get going with the CPR skills - the devices clearly aren't working (and yes, they can fail just like anything else).

In 2 rescuer CPR, one gives the breaths, the other person gives rescue breathing.

Yes you can from American Red Cross. You must first pass the test though.

CPR was first demonstrated as a successful technique in 1954, so it's been around 50+ years.

Because it stimulates the heart to 'reset' itself.

You are trying not to break the xiphoid process bone.

An ACLS nurse must continue CPR until a doctor pronounces the patient expired, if the patient shows signs of life, or you are too tired to continue and there is no one else to take over CPR.

The proper location is about two fingers width below the Xiphoid process (the peice of cartilage between the ribs.) This is more between the ribcage and not below it.

Instead of using abdominal thrusts, chest thrusts are used. The fists are placed against the middle of the breastbone, and the motion of the chest thrust is in and downward, rather than upward

The emergency cardiac care recommendations, adopted by AHA and ARC, are what is followed as the best care for an infant.
