UNLABELLED: This study was carried out to establish the length of time over which an individual can maintain effective chest compressions and the most effective pattern of rest and handover among a team. The continuing effectiveness of chest compressions was compared between groups of 2 or 3 rescuers performing chest compressions for 1, 2 or 3 min during scenarios lasting 18 min. Evaluation of the effectiveness of compressions was achieved using a computerised resuscitation manikin (Laerdal/Skillmeter) on a hospital trolley. Twenty-one volunteers competent in basic life support participated. The results were analysed using one-way analysis of variance and Dunnett's contrast of the various scenarios. The results demonstrated that a three person team delivering 1 min periods of chest compressions in rotation is significantly better than other sequences at 5 min and beyond (P<0.0001). At 18 min 91.5% of all chest compressions delivered by this three person team were greater than 70% effective. There was no significant difference between the first and final set of chest compressions. CONCLUSION: Continuous chest compressions performed for 1 min, preferably by three rescuers in rotation, maintain a high level of effectiveness. Longer periods of chest compressions should be discouraged.
