What are effective chest compressons?

To ensure effective chest compressions during CPR:

Depth: Compress the chest at least 2 inches (5 cm) but not more than 2.4 inches (6 cm) deep.

Rate: Aim for a compression rate of 100 to 120 compressions per minute. Maintain a steady rhythm.

Full Recoil: Allow the chest to fully recoil after each compression. This allows blood to flow back into the heart.

Hand Position: Place the heel of one hand on the center of the person's chest, between the nipples. Place your other hand over the first hand and interlock your fingers. Keep your fingers off the person's chest.

Lean: Position yourself directly above the person's chest with your shoulders directly over your hands. Use your body weight to generate compression force.

Minimize Interruptions: Avoid excessive pauses between compressions. Only interrupt compressions for a necessary, such as giving rescue breaths or checking the person's responsiveness.

Coordinate: If multiple rescuers are performing CPR, ensure your compressions are coordinated with rescue breaths. One rescuer should be giving compressions while the other provides breaths.

Switch Compressors: If you're performing CPR alone and become exhausted, switch to the "hand-over-hand" technique to maintain a steady compression rhythm. Place your near hand over the farthest hand and use the weight of your upper body to compress the chest.

Recheck: Occasionally pause compressions to check the person's responsiveness and airway for any obstructions.

Effective chest compressions require practice to master. Regular training in CPR techniques can help you perform them confidently and efficiently in an emergency situation.
