Brief Summary
Optimal chest compression depth during CPR is 4.56cm which is at variance with the current guidelines of 5.0-6.0cm. A change in guidelines is only worthwhile if healthcare professionals can accurately judge a subtle reduction in chest compression depth during CPR by a relatively small amount.
