I just completed a CPR and AED training class.
Things sure have changed in the decade since I last took one of these classes.
No more extensive checks for breathing, no more breathing before compressions, no checking for a pulse, no messing around elevating the feet, no checking the airway.
First you assess the area. Becoming a victim yourself does not help the person already on the ground, check for dangerous objects or conditions.
Followed by assessing the victim. Try and get a response. Yell at em. Touch em, maybe shake them. If you don't get a response, check for breathing by looking for chest movement and listening.
This is also where you might attempt to figure out if they have been like this for a long while or not. If they are approaching room temperature, I'm not real sure CPR is appropriate.
If they aren't breathing, you immediately start chest compressions. 30 fast chest compressions, and if you are comfortable, two quick rescue breaths. Remember, a breath for them, a breath for you, another breath for them, then 30 more fast chest compressions. You can wait for the breathing mask that most AED's seem to come with before starting the breathing if you are totally unprepared to do it mouth to mouth, just keep up the chest compressions. You're looking for around 100 compression a minute.
If/When the nice person comes back with the AED, they should do the quick setup. Getting rid of the clothing while doing chest compressions should be interesting, as should shaving contact patches through any Wookiee suit worthy chest hair. Hopefully the second person will be doing that while you continue on with the chest compressions, otherwise you are going to really have your hands full.
Position the AED pads so that the charge will go through the heart. One standard position is up at the shoulder/arm pit area and down toward the opposite hip. Be mindful of the position though, worst case front and back will work, but then you have to roll the person.
The nice AED will do it's own assessment, but you can't touch the person while it's doing it. If needed, it will instruct you to not touch the patient and to hit the nice flashing button (or not, it might be automatic). Back to compressions and breathing for two minutes, then it assesses again.
Wash, rinse, repeat until the nice men in the big box on wheels show up and take over.
You don't breath as often as I remember, and they want the chest compressions to be much quicker. They really stressed getting the chest compressions started as soon as possible. Getting the blood flowing to the brain is the most important issue, there is already oxygen in the blood stream, getting that oxygenated blood to the brain can greatly improve quality of life for the victim.
Was very entertaining. I was in the second ever class, and the instructor says it was much more enjoyable than the first class.
As I said, it's the first training of this sort I've done in over a decade, and it seems to have wet my whistle. I am very interested in getting more training in first aide, and even limited trauma.
