Chest compression fraction during out of hospital cardiac arrest. Substudy of the CAAM trial

This dataset originates from supplementary data collected during a non-inferiority trial comparing Bag valve ventilation to Endotracheal intubation (CAAM trial). The research hypothesis was to test whether Endotracheal intubation would lead to a reduction in no flow time during CPR for out of hospital cardiac arrest. Data were collected through a Corpuls 3 allowing simultaneous synchronized recording of impedance, ambient audio and ECG. These data were re-analyzed by two researchers (Frédéric Cavallotto and Diane de Longueville) allowing through the use of the audio ambient recording a correct characterization of any pause in chest compression into predefined categories such as Ventilation, Intubation, Rythm analysis, LUCAS placement... These data were merged to produce this dataset with Ustein Style variables collected after CPR for each patient.
