THE CAPABILITY OF PROFESSIONAL AND LAY RESCUERS TO ESTIMATE THE GIVEN CHEST COMPRESSION TARGET DEPTH

There is an on-going discussion on quality of cardiopulmonary resuscitation (CPR) as related to guideline target values for chest compression depth. Deeper compression depth is generally understood to be more effective. Interestingly, the American Heart Association (AHA) guideline requests a compression depth of “at least 5cm” whereas the European Resuscitation Council (ERC) guideline requests “at least 5 cm, but not to exceed 6 cm”. It is unknown which recommendation is more effective to achieve a correct compression depth.  This study attempted to determine the...

COMPRESSION DEPTH DURING PROTOCOL-DRIVEN TELEPHONE-ASSISTED CARDIOPULMONARY RESUSCITATION IS NOT IMPROVED BY REPETITIVE OR INTENSIFIED INSTRUCTIONS.

In telephone-assisted cardiopulmonary resuscitation (T-CPR), protocols are used to help the bystander via standardized instructions. However, the requested compression depth is rarely achieved. This study was designed to investigate the effect of intensified wording and/or repetitive target depth instructions on compression depth. Methods: In this investigator-blinded, randomized, 4- armed, factorial study, 32 volunteers were requested to perform 10 minutes of compression only- CPR on a manikin. Participants were randomized either to standard wording (“push down 5cm”),...

TELEPHONE-ASSISTED BYSTANDER COMPRESSION-ONLY CPR: DOES “PUSH AS HARD AS YOU CAN” ENHANCE CHEST COMPRESSION DEPTH

In telephone assisted, advanced medical priority dispatch system (AMPDS) driven, lay-rescuer, compression-only cardiopulmonary resuscitation (COCPR) it remains unclear whether the instruction “push as hard as you can” improves compression depth. Methods: This was a prospective, experimental, double-blinded, randomized, controlled, parallel group study to compare the depth of chest compressions achieved following the instruction “push as hard as you can” and the recommended guidelines. Primary outcome was defined as compression depth. Secondary outcomes were defined as...
