Answer:

1) condition in which the force of the blood against the artery walls is too high.

Usually hypertension is defined as blood pressure above 140/90, and is considered severe if the pressure is above 180/120.

2)CPR stands for cardiopulmonary resuscitation. It is an emergency life-saving procedure that is done when someone's breathing or heartbeat has stopped. This may happen after an electric shock, heart attack, or drowning. ... Chest compressions keep oxygen-rich blood flowing until the heartbeat and breathing can be restored.
