CPR first aid technique. Artwork showing the 4th of 6 steps used in the first aid technique of cardiopulmonary resuscitation (CPR). Here, faced with a non-breathing patient, the first aid responder is carrying out mouth-to-mouth resuscitation (blowing steadily into the patient's mouth). This is followed by checking the patient's pulse. For the full sequence, see C014/5610 to C014/5615.
