BACKGROUND High-quality cardiopulmonary resuscitation (CPR) by laypersons is a key determinant of both outcome and survival for out-of-hospital cardiac arrest. Dispatcher-assisted CPR (telephone-CPR, T-CPR) increases the frequency and correctness of bystander-CPR but results in prolonged time to first chest compressions. However, it remains unclear whether instructions for rescue ventilation and/or chest compressions should be recommended for dispatcher-assisted CPR. OBJECTIVE The aim of this study was to evaluate both principles of T-CPR with respect to CPR quality. DESIGN Randomised controlled single-blinded manikin trial. SETTING University Hospital of Cologne, Germany, 1 July 2012 to 30 September 2012. PARTICIPANTS Sixty laypersons between 18 and 65 years. Medically educated individuals, medical professionals and pregnant women were excluded. Participants were asked to resuscitate a manikin and were randomised into three groups: not dispatcher-assisted (uninstructed) CPR (group 1; U-CPR; n = 20), dispatcher-assisted compression-only CPR (group 2; DACO-CPR; n = 19) and full dispatcher-assisted CPR with rescue ventilation (group 3; DAF-CPR; n = 19). MAIN OUTCOME MEASURES Specific parameters of CPR quality [i.e. no-flow-time (NFT) as well as compression and ventilation parameters] were analysed. To compare different groups we used Student's t test and P less than 0.05 was considered significant. RESULTS Initial NFT was lowest in the DACO-CPR group (mean 21.3 +/- 14.4%), followed by dispatcher-assisted full CPR (mean 49.1 +/- 8.5%) and by unassisted CPR (mean 55.0 +/- 12.9%). Initial NFT covering the time of instruction was lower in DACO-CPR (12.1 +/- 5.4%) as compared to dispatcher-assisted full CPR (20.7 +/- 8.1%). Compression depth was similar in all three groups: 40.6 +/- 13.0mm (unassisted CPR), 41.0 +/- 12.2 mm (DACO-CPR) and 38.8 +/- 15.8 mm (dispatcher-assisted full CPR). Average compression frequency was highest in the DACO-CPR group (65.2 +/- 22.4 min(-1)) compared with the unassisted CPR group (35.6 +/- 24.2 min(-1)) and the dispatcher-assisted full CPR group (44.5 +/- 10.8 min(-1)). Correct rescue ventilation was given in 3.1 +/- 11.1% (unassisted CPR) and 1.6 +/- 16.1% (dispatcher-assisted full CPR) of all ventilation attempts. CONCLUSION Best quality of CPR was achieved by DACO-CPR because of superior compression frequencies and reduced NFT. In contrast, the full dispatcher-assisted CPR with a longer initial instructing phase (initial NFT) did not result in enhanced CPR quality or an optimised compression depth.
