%X Objectives To analyse changes in the quality of cardiopulmonary resuscitation (CPR) according to driving patterns encountered during ambulance transport, using a virtual reality simulator.

Design Prospective, cross-over, randomised study.

Setting This study was conducted at the National Fire Service Academy, Cheonan-si, Korea.

Participants Emergency medical technicians (39 men and 9 women) attending the National Fire Service Academy for clinical training with ĦŬ6 months field experience or having performed ĦŬ10 CPR. Individuals who withdrew consent were excluded.

Outcome measures CPR quality parameters (eg, chest compression depth and its variability).

Results Chest compressions were performed for 8£żmin each in a stationary and driving state. The mean chest compression depths were 54.8£żmm and 55.3£żmm during these two states, respectively (p=0.41). The SD of the chest compression depth was significantly higher while in the driving (7.6£żmm) than in the stationary state (6.5£żmm; p=0.04). The compression depths in the speed bump and sudden stop sections were 51.5£żmm and 50.6£żmm, respectively, which was shallower than those in all other sections (p<0.001). The correct hand position rate was low in the speed bump, sudden stop and right-hand cornering sections (65.4%, 71.5% and 72.5%, respectively; p=0.001)

Conclusions Although we found no differences in chest compression quality parameters between the stationary and driving states, the variability in the chest compression depth increased in the driving state. When comparing CPR quality parameters according to driving patterns, we noted a shallower compression depth, increased variability and decreased correct hand position rate in the speed bump, sudden stop and right-hand cornering sections. The clinical significance of these changes in CPR quality during ambulance transport remains to be determined. Future studies on how to reduce changes in the quality of CPR (including research on equipment development) are needed
