6.0 Integration with Cardiopulmonary Resuscitation (CPR)
In cardiac arrest, ventilation and chest compressions have a symbiotic relationship. Ventilation without circulation is futile, as the oxygen has no way to reach the brain. Likewise, compressions without ventilation merely circulate deoxygenated blood. Both must be performed together as integrated Cardiopulmonary Resuscitation (CPR).
A high-performance CPR cycle consists of the following components:
- Compression-to-Ventilation Ratio: The universal ratio is 30 chest compressions to 2 rescue breaths.
- Adult Chest Compressions: Place the heel of one hand on the lower half of the sternum. Place your other hand on top. Compress the chest to a depth of 5-6 cm at a rate of 100-120 compressions per minute. Allow for full chest recoil between compressions.
- Infant Chest Compressions: Use two fingers (index and middle) on the lower half of the sternum. Compress the chest to a depth of approximately 4 cm at a rate of 100-120 compressions per minute.
- Cycle Continuation: Continue the 30:2 cycle without interruption until professional medical help arrives, the patient shows signs of life, or you are physically unable to continue.
