5.  What is the definition for, "pushing blood through the body through chest compressions"?

The definition for "pushing blood through the body through chest compressions" refers to the process involved in cardiopulmonary resuscitation (CPR). Here are the steps:

1. Chest compressions are a way to simulate the heart's function of pumping blood. When the heart stops beating during a cardiac arrest, blood stops flowing throughout the body. This can lead to brain damage or death.

2. To prevent this, chest compressions are performed. The rescuer places their hands on the center of the person's chest (usually the lower half of the breastbone) and pushes hard and fast. This applies pressure on the heart, causing it to pump blood.

3. The compressions help to circulate blood to vital organs such as the brain and heart. This is crucial in keeping the person alive and reducing the risk of brain damage.

4. The standard rate for chest compressions is 100 to 120 compressions per minute. The depth of the compressions should be at least 2 inches (5 centimeters) but not greater than 2.
