Measurement of tidal volumes and respiratory rate during regular and asynchronous intra-arrest ventilation using the EOlife X device: A method-comparison study in a porcine cardiac arrest model

The authors aimed to evaluate the accuracy of the EOlife X ventilation feedback device during both regular and intra-arrest ventilation in a porcine cardiac arrest model. They found that while the device performed within clinically acceptable limits during regular ventilation, it significantly deviated from these limits during intra-arrest ventilation, likely due to the effects of chest compressions on airflow measurements. This study highlights the need for specific validation of ventilatory monitoring devices under CPR conditions.
