Randomized Controlled Trial
Effects of training time and feedback on ventilation skills in lay rescuers.
Lay rescuers have difficulties acquiring ventilation skills during training. Non-feedback manikins are still widely employed, although skill acquisition is suboptimal. We analysed if a longer training time and verbal feedback, given by an instructor, improved ventilation skill acquisition with non-feedback manikins. ⋯ Both 10 and 20 min ventilation training times resulted in comparable skills. Volunteers hyperventilated the manikin and produced excessive stomach inflation in this model. This increased even further after verbal feedback.
