Abstract 14241: Simulation Study of Effect of a Novel Ventilation Feedback Device Combined With Just-in-time, Just-in-place Ventilation Training
Introduction: Directive feedback devices improve chest compression quality and may improve skill acquisition and retention during training, and are therefore recommended in current resuscitation guidelines. Current feedback devices guide chest compressions, but ventilation quality is largely ignored. The objective of this study was to evaluate whether professional in-hospital advanced life support providers who receive ventilation training with continuous ventilation feedback, compared to no ventilation training and feedback, had improved CPR performance during a simulated CPR and post-ROSC scenario.
Methods: Twenty in-hospital advanced life support teams were randomized to either ventilation feedback augmented training or control, and tested in a simulated cardiac arrest and post-ROSC scenario. Scenarios were performed on adapted SimMan 3G manikins and data was collected using LLEAP software (both: Laerdal Medical, Stavanger, Norway). Primary outcome was ventilation quality during CPR and immediately post-ROSC (percentage of 30-second- segments with respiratory rate within guideline recommended range 4-10 ventilations/minute during CPR and 6-15 ventilations/minute post-ROSC).
Results: Two of the teams with ventilation feedback had to be excluded due to technical issues with the feedback device leaving 8 teams with feedback and 10 teams without feedback. After intubation the teams with feedback had median (IQR) 80 % (58-94) of 30-second-segments with 4-10 ventilations/minute compared to 42 % (11-85) for the group without feedback (p=0.068). The group with feedback was significantly more compliant with current guidelines with none 30-seconds-segments with hyperventilation (> 20 ventilations/minute) compared to the group without feedback where 5 of the teams had segments with hyperventilation (p=0.036). The median (IQR) ventilation rates during CPR were 12 /minute (10-15) in the groups with feedback and 18 /minute (12-24) in the groups without feedback (p=0.12). There were no significant differences in any ventilation parameters between the two groups before intubation and post-ROSC.
Conclusions: Training with the use of a continuous ventilation feedback device improved ventilation performance during simulated CPR.
