When someone has drowned and we try to save him we give him a 'kiss of life'? Is it true or do you have a more common term?
In AmE, "kiss of life" would be understood as mouth-to-mouth resuscitation, but the most common term for that procedure is CPR, which is an abbreviation for cardiopulmonary resuscitation. For example, if a person untrained in the proper mouth-to-mouth resuscitation procedure pulled a drowning person out of the swimming pool, he would immediately call out to the bystanders "Does anyone here know CPR??"
If someone has simply stopped breathing, but their heart is still beating, it's important not to do the chest compressions as this can cause serious heart damage. You would only do the full procedure if the person has stopped breathing AND their heart has stopped.
'CPR' is the term I'd use, but I used to be a first-aider. The reason for using it is that mouth-to-mouth breathing is useless unless the heart is going; (manual CPR is pretty useless as well - about 7% successful I was told - but not as useless )
