Methods 19 paramedic teams each consisting of three paramedics performed ALS for 12 minutes with the same paramedic providing all chest compressions. The patient was a resuscitation manikin found in ventricular fibrillation VF . The first shock terminated the VF and the patient remained in pulseless electrical activity PEA throughout the scenario. Average chest compression depth and rate was measured each minute for 12 minutes and divided into three groups based on chest compression quality good compression depth 40 mm compression rate 100-120 minute for each minute of CPR bad initial compression depth 40 mm initial compression rate 100 or 120 minute or decay change from good to bad during the 12 minutes . Changes in no-flow ratio NFR defined as the time without chest compressions divided by the total time of the ALS scenario over time was also measured. Results Based on compression depth 5 26 9 47 and 5 26 were good bad and with decay respectively. Only one paramedic experienced decay within the first two minutes. Based on compression rate 6 32 6 32 and 7 37 were good bad and
