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.
High Quality Chest Compressions for Effective CPR
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. However, Good Samaritan laws exist in most jurisdictions to protect individuals who voluntarily provide emergency care.
Inadequate recoil reduces the pressure in the chest and diminishes the volume of blood returned to the heart, thereby reducing the effectiveness of each compression. When circulation stops, the brain, which is highly sensitive to oxygen deprivation, begins to suffer irreversible damage within just four to six minutes.
