Positioning for CPR is as follows:
• CPR is most easily and effectively performed by laying the patient supine on a relatively hard surface, which allows effective compression of the sternum
• Delivery of CPR on a mattress or other soft material is generally less effective
• The person giving compressions should be positioned high enough above the patient to achieve sufficient leverage, so that he or she can use body weight to adequately compress the chest
For an unconscious adult, CPR is initiated as follows:
• Give 30 chest compressions
• Perform the head-tilt chin-lift maneuver to open the airway and determine if the patient is breathing
• Before beginning ventilations, look in the patient’s mouth for a foreign body blocking the airway
