Chain of Survival: Integration with Emergency Response The effectiveness of CPR is best understood within the framework of the "Chain of Survival," a sequence of critical actions that significantly improve the odds of survival following sudden cardiac arrest. CPR manually compresses the heart between the spine and the breastbone, pushing blood through the systemic circulation to vital organs, particularly the brain, until a defibrillator can be used to correct the heart's rhythm or advanced medical personnel take over.

Conventional CPR The standard protocol for lay rescuers has evolved to simplify the process and encourage action. Without immediate CPR, the chance of survival decreases by 7 to 10 percent with each passing minute, making it a skill that separates life from death in those crucial initial moments.
Compression Depth and Rate To generate adequate blood flow, current guidelines emphasize the importance of compression depth. These laws generally shield a rescuer from liability, provided they act in good faith, at the level of care expected of a reasonable person, and without expectation of compensation.

It is vital to allow the chest to recoil completely between compressions to allow the heart chambers to refill with blood. Conventional CPR, which includes rescue breaths, is still essential for specific scenarios, such as cases involving infants, children, or adults whose cardiac arrest is due to drowning or other asphyxial causes, where oxygenation of the blood is a primary concern.
