CPR should be reassessed every 2 minutes to determine if the person shows any signs of life or if the situation changes. Continue CPR until medical professionals arrive or the person starts to show signs of life.
Chest compressions should be performed at a rate of 100-120 compressions per minute, which is about the tempo of the song “Stayin' Alive” by the Bee Gees. This rate helps ensure sufficient blood circulation to vital organs.
Before performing CPR, it’s critical to ensure emergency services are on the way. Activating the emergency response system or calling for help allows trained professionals to assist and ensures the person gets the appropriate care.
For adult CPR, the correct ratio is 30 chest compressions to 2 rescue breaths. This ratio allows for continuous blood circulation while providing oxygen to the body.
The correct hand placement for chest compressions is to place the heel of one hand on the center of the chest (lower half of the breastbone) and place the other hand on top, interlacing fingers. This provides effective compressions.
Chest compressions for an adult should be at least 2 inches deep to be effective in circulating blood to the heart and brain. Compressing too shallow may not provide enough blood flow.
An AED should be used as soon as it is available. The device will guide the user through the process of delivering a shock if needed. It is vital to follow the AED's voice or visual prompts to deliver proper treatment.
