Ventilation feedback devices inaccurate during CPR
Accuracy of ventilation feedback devices compared with a reference standard during asynchronous ventilation with continuous chest compressions in a simulated cardiac arrest: a prospective non-randomized cross-over study
Resuscitation Plus · Added 8 September 2026
Simulation cross-over study of two commercial ventilation feedback devices used during continuous compressions with asynchronous ventilations — both were clinically inaccurate, one displaying 111 breaths/min when the true rate was 12 and underestimating tidal volume by up to 440 mL in reversed airflow.
- Study type
- Simulation
- Design
- Prospective, simulation-based, non-randomised cross-over study
- Participants
- 20 emergency department nurse practitioners ventilating an intubated manikin (254 and 222 ventilations analysed)
- Main finding
- EOLifeX® overestimated ventilation rate (111/min displayed vs 12/min true; bias +99 breaths/min) and underestimated tidal volume (104 mL vs 544 mL; bias -440 mL); AccuVent® displayed accurate rate but underestimated tidal volume (360 mL vs 532 mL; bias -172 mL)
- Caveat
- Manikin simulation with reversed airflow conditions; only two devices tested
- Bottom line
- Context only
Why it matters in Australia (Medium relevance). transferability — cautionary tale for relying on feedback displays during asynchronous CPR
Learning goal
Weigh the reliability of ventilation feedback devices when guiding ventilations during continuous chest compressions.
