100-120 chest compressions should be perfor...

100–120 chest compressions per minute should be performed during CPR because this rate is proven to give the best blood flow to the brain and heart while still allowing the chest to recoil between compressions.

What “100–120 compressions per minute” really means

Think of it as a rhythm: you are aiming for about 2 compressions every second, steady and uninterrupted.

This rate is recommended in major CPR guidelines for adults, children, and infants (with depth and technique adjusted by age).

Key points:

  • Target rate: 100–120 chest compressions per minute.
  • Depth (adult): about 5–6 cm (2–2.4 inches), with full chest recoil after each push.
  • Example mental cue: many instructors use the beat of “Stayin’ Alive” because its tempo is close to this range (roughly 100–120 beats per minute).

Why this specific range matters

Research and guidelines show:

  • Below ~100/min: blood flow to the brain and heart drops, reducing chances of survival.
  • Around 120/min: blood flow is near optimal, as shown in animal and human studies of chest compression rates.
  • Much faster than 120/min: compressions often become too shallow and the chest may not fully recoil, which lowers effectiveness and can cause more injury.

So the range 100–120/min is a sweet spot : fast enough for good circulation, slow enough to maintain proper depth and technique.

Brief “exam-style” clarification

If you see a statement like:

“100–120 chest compressions should be performed on the patient per minute.”

In the context of modern CPR guidelines, that statement is True for the recommended compression rate during high‑quality CPR, assuming proper depth and recoil.

Simple mental picture

Imagine you start compressions on someone in cardiac arrest:

  1. You place your hands in the center of the chest and lock your elbows.
  2. You push hard and fast, aiming for a steady 2 pushes per second, counting in your head or to a familiar song with a similar beat.
  1. You do not stop unless the person shows signs of life or trained help or an AED takes over.
