Study Notes

The Heart and Blood Flow

The heart pumps blood through the lungs, where it takes in oxygen and releases carbon dioxide.
Oxygenated blood returns to the heart and is pumped out to vital organs, including the heart, brain, liver, kidneys, and lungs, as well as the rest of the body.

Cardiac Arrest

When the heart stops working, blood flow stops, and the person quickly becomes unconscious.
Without blood flow, the heart and brain quickly become damaged due to lack of oxygen.

Basic Life Support (BLS)

BLS tries to prevent or slow damage to vital organs until the cause of the problem can be corrected.
BLS improves a person's chance of surviving until advanced care becomes available.

Keys for BLS

Quickly start the Chain of Survival.
Deliver proper chest compressions to circulate oxygen to the brain and vital organs.
Know when and how to use an Automated External Defibrillator (AED).
Provide rescue breathing.
Understand how to work with other rescuers as part of a team.
Know how to treat choking.
