Many research papers, including CPR-2 and CPR-3, show that supgraglottic airway (SGA) devices have unique properties that set them apart from bag-valve-mask (BVM) devices and tracheal intubation (TI).

To better acknowledge these differences and motivate fellow researchers to specifically assess the impact of SGA devices, we recently published a viewpoint in Healthcare (MDPI): Suppan, L.; Fehlmann, C.A.; Stuby, L.; Suppan, M. The Importance of Acknowledging an Intermediate Category of Airway Management Devices in the Prehospital Setting. Healthcare 2022, 10, 961. https://doi.org/10.3390/healthcare10050961

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.

Hot on the heels of our first pulication ("CPR-1"), which described our study protocol (Effect on Chest Compression Fraction of Continuous Manual Compressions with Asynchronous Ventilations Using an i-gel® versus 30:2 Approach during Simulated Out-of-Hospital Cardiac Arrest: Protocol for a Manikin Multicenter Randomized Controlled Trial) we are dellighted to announce that the study has now been completed and published in the Journal of Clinical Medicine (MDPI).

Our group's first publication ("CPR-1"), Effect on Chest Compression Fraction of Continuous Manual Compressions with Asynchronous Ventilations Using an i-gel® versus 30:2 Approach during Simulated Out-of-Hospital Cardiac Arrest: Protocol for a Manikin Multicenter Randomized Controlled Trial, was published in Healthcare (MDPI) in March 2021.
