What to do for CPR.
The Heart and Stroke Foundation actually suggests that you do CAB instead of ABC.
Check for Circulation first, if a person is bleeding and has a main
artery cut, they will die a lot sooner then they would if they are
without oxygen for a few minutes. They have a good point here, if a
person bleeds out, that is irreversible, there is nothing you can do to
fix that, but if a person dies because of a heart attack, they can be
brought back. I have personally witnessed this, from the time this
person had a heart attack till the paramedics got their first heart beat
was 45 minutes. Goes to show that you shouldn't give up CPR too soon. This
person, six years later, has only some short term memory loss.
you would do any type of checking, you would first check around where
the person is lying to see if there are any other dangers that could
harm you. If you put yourself in danger trying to help someone, you may
both die and accomplish nothing, so always make sure it's safe to
approach a person before you do anything to help. The normal also is to
delegate and have someone call 911, but if your by yourself, you would
try to assess the situation first and see if the person has a pulse
before you would make the call, depending on the situation, there might
not be anyone to call.
Using the diagram below you would first do figure D and check circulation, especially for bleeding, then you would go to figure A and check the airway. You want to make sure there are no obstructions in the persons mouth before doing CPR, let say the person happens to have a piece of gum or food in their mouth, you could end up blowing the gum or food down their throat and causing a bigger problem, so do a sweep of their mouth with your finger to make sure there is nothing there to complicate things. When you tilt the head back to open the passageway up better as in figure B, if you have a shirt or towel rolled up to put under the persons neck, this will help keep the persons head in this position much easier.
If the person does not have a pulse and are
not breathing you would start by doing chest compressions. You want to
place the heel of your hand in the middle of the chest, on the
breastbone and in between the nipples as shown in figure E. Now place your other hand on top of this hand
and interlace your fingers. Keeping your arms stretched out straight in front of you, on an adult, you want to compress the chest
about 2 inches and then release so that the chest recoils before
compressing again, your aiming for about 100 compressions per minute, but
only do 30 and then check for breathing, this should take you about 18 seconds to do 30 compressions. If the person isn't breathing after the compressions, start giving them mouth to mouth resuscitation.
When giving mouth to
mouth you want to squeeze the person's nose closed so as not to lose
any air when you're blowing into their mouth. Watch to see if their chest
rises as your gently blowing in their mouth, if it does not, recheck the airway
and try again. Only do this twice and then go back to giving 30
compressions even if their chest does not rise after the second try. If air is going into their chest, then allow the air to release, (the chest will return to normal), before blowing in again. You have to keep trying to do these rotations until the person either starts breathing on
their own, or until help comes. If no one comes to help and you get too tired to continue on, then you'll have to let them go, but at least you will have made an effort to keep this person alive.
When doing CPR, they claim that the compressions are more important than doing mouth to mouth resuscitation. When your doing compressions, you're pumping blood to the brain which is more important than oxygen at this point.
