When performing CPR, how deep should compressions be in adults?

When performing CPR on adults, chest compressions should be at least 2 inches deep. This depth is critical because adequate compression depth ensures that the heart can effectively pump blood to vital organs, particularly the brain and heart itself. This depth helps to improve blood circulation during cardiac arrest, leading to a better chance of survival and neurological function after resuscitation.

The recommendation for a minimum depth of 2 inches is based on extensive research that indicates this level of compressions produces sufficient pressure to generate effective blood flow. It is also important to remember that compressions should be performed at a rate of 100 to 120 per minute, allowing for effective ventilation and the best possible outcomes for the patient.
