It is compression quality that counts when it comes to cardiopulmonary resuscitation.

A systematic review and meta-analysis conlcudes that deeper chest compressions and rapid rates of compression are associated with significantly improved survival from cardiac arrest.

Survivors were significantly more likley to have received chest compression rates closer to 85-100 compressions per minute than non-survivors.

No significant difference in no-flow fraction or ventilation rate was detected between those who survived and those who did not.
