Fig. 2From: Feasibility of HEMS performed prehospital extracorporeal-cardiopulmonary resuscitation in paediatric cardiac arrests; two case reportsVisualising time consuming variables in (E-)CPRLegenda: time-consuming variables in (E-)CPR with in-hospital cannulation (A) versus pre-hospital cannulation (B) as well as the timeframes of both case reports (C)Blue delineated components can be mitigated by proper training, red delineated components are rather fixed. The optional component 9 (dotted red line) is depending on E-CPR activation method and the geographic distance to be covered. The orange shaded components (A 5–7) poses a particular challenge with CPR in-transit in resource limited environment, especially in children. These variables are omitted from low-flow time in case of pre-hospital cannulationAbbreviations: BLS = Basic Life Support, AED = Automated External Defibrillator, ALS = Advanced Life Support, E-CPR = Extracorporeal-CardioPulmonary Resuscitation, ECLS = ExtraCorporeal Life Support, ROSC = Return of Spontaneous CirculationBack to article page
