Abstract P166: Objective Assessment of Cardiopulmonary Resuscitation Skills of 10–11 Year Old Schoolchildren Using Two Different External Chest Compressions to Ventilation Ratios
AIMS: To objectively evaluate how effectively children can perform CPR and establish whether or not their performance is affected by the ratio of external chest compressions to ventilations used.
METHODS: 85 school children aged 10–11 years old were randomised into two groups and asked to perform CPR on a Laerdal resuscitation skills reporter manikin for 3 minutes at a ratio of 30:2 followed by 5 minutes rest, then for 3 minutes at 15:2 (or vice versa). Chest compression depths and ventilation volumes were recorded on a laptop computer and analysed using the Hills and Armitage cross over trial design.
RESULTS: In both groups the percentage of effective chest compression was greater when the 15:2 ratio was used (P<0.001). The average chest compression depth was significantly greater when the children were performing CPR at a ratio of 15:2 (P<0.001). The compression to ventialtion ratio used did not affect the average volume or percentage of effective ventilations given. However, in both groups, the ventialation variables showed enhanced performance during the second period of CPR.
CONCLUSIONS: Children as young as 10 years are capable of performing effective CPR. This age group perform more effective CPR when using a ratio fo 15:2 rather than 30:2. We recommend that the age of the rescuer should be taken into consideration for future resuscitation guidelines, particularly if basic life support training is to be introduced into schools.
