Final answer:
CPR stands for cardiopulmonary resuscitation. It is a life-saving technique used to maintain blood flow to vital organs when the heart stops beating. Chest compressions are performed at a rate of 100 per minute until the patient recovers or is declared dead.
Step-by-step explanation:
CPR stands for cardiopulmonary resuscitation. It is an emergency technique used to maintain blood flow to the brain and other vital organs when the heart stops beating.
In CPR, pressure is applied to the sternum (the area between the lines at T4 and T9) to manually compress the blood within the heart and push it into the pulmonary and systemic circuits. The compression depth should be at least 5 cm deep and at a rate of 100 compressions per minute.
High-quality chest compressions are the emphasis during CPR, rather than providing artificial respiration. CPR should be performed until the patient regains spontaneous contraction or is declared dead by an experienced healthcare professional.
