Six dial mechanical ventilation strategy versus self inflating adult bag valve ventilation in adult cardiac arrest patients undergoing chest compressions- A Randomized Crossover Non-Inferiority trial

The American Heart Association estimates that approximately 1000 cardiac arrests occur each day. The American Heart Association updated its recommendations in 2020 and suggested that a tidal volume of approximately 500 to 600 ml, sufficient to cause a visible chest rise, provides adequate ventilation while minimising the risk of overdistension or gastric inflation. Airway management and ventilation during CPR are essential for successful resuscitation in these patients. Studies have compared mechanical ventilation with bag-valve ventilation for gas exchange and have shown that mechanical ventilation is at least feasible and safe for use during CPR in intubated cardiac arrest patients. Another study, using a physical model during simulated cardiopulmonary resuscitation, found that conventional ventilation modes during simulated CPR manoeuvres produced pressures and volumes similar to those reported with bag-valve masks. Studies have yet to be conducted to determine the efficacy of tidal-volume delivery via mechanical ventilation and bag-valve ventilation in cardiac arrest patients. This study will evaluate the efficacy of tidal volume delivery during mechanical ventilation versus bag-valve ventilation in adult intubated cardiac arrest patients undergoing cardiopulmonary resuscitation in the emergency medicine department.
