Re: A life saving skill.......
Basic first aid esp a little CPR knowledge can aid the ambulance technicians and paramedics in to giving the person a better survival rate, As MBK said in her training if your not happy doing the breaths just concentrate on chest compressions.
After 2 good breaths (full and equal air pressure into both lungs) it'll take approx 20 good compressions for the full body to recieve that o2, and in 10 compressions you would be stopping to give more o2. Although not official, current thinking from resus council (it's under review at the moment) is to go straight into 300 compressions, after calling for help, as there is still over 70% o2 in the air we breathe out and the compressions will enable the brain to stay oxygenated.
Although on a very sick note, the sound of cracking ribs as you do those first couple of compression is a sound of beauty.
