Summary There is a discrepancy between resuscitation teaching and witnessed clinical practice. Furthermore, deleterious outcomes are associated with hyperventilation. We therefore conducted a manikin‐based study of a simulated cardiac arrest to evaluate the ability of three ventilating devices to provide guideline‐consistent ventilation. Mean (SD) minute ventilation was reduced with the paediatric self‐inflating bag (7.0 (3.2) l.min −1 ) compared with the Mapleson C system (9.8 (3.5) l.min −1 ) and adult self‐inflating bag (9.7 (4.2) l.min −1 ; p = 0.003). Tidal volume was also lower with the paediatric self‐inflating bag (391 (52) ml) compared with the others (582 (87) ml and 625 (103) ml, respectively; p < 0.001), as was peak airway pressure (14.5 (5.2) cmH 2 O vs 20.7 (9.0) cmH 2 O and 30.3 (11.4) cmH 2 O, respectively; p < 0.001). Participants hyperventilated patients’ lungs in simulated cardiac arrest with all three devices. The paediatric self‐inflating bag delivered the most guideline‐consistent ventilation. Its use in adult cardiopulmonary resuscitation may ensure delivery of more guideline‐consistent ventilation in patients with tracheal intubation.
