Our second publication ("CPR-2") unexpectedly revealed that using an i-gel® device was associated with significantly shallower chest compressions. Different hypotheses were drawn to explain this finding and we theorized that the bulk of the airway management apparatus could lead to shallower compressions when the rescuer was positioned at the patient's head. 

We therefore carried out a post-hoc analysis ("CPR-3") to determine the impact of the over-the-head position on chest compression depth and rate when a supraglottic airway device was used.
