Improving access to extracorporeal membrane oxygenation for out of hospital cardiac arrest: pre-hospital ECPR and alternate delivery strategies

Table 2 Summary of the performance of each delivery strategy

Strategy	Key model assumptions	Paramedic on-scene time (mins)	Cannulation time (mins)	Population able access ECPR < 1 h	Survival probability across the city (%)
In-hospital ECPR	5 current ECPR capable hospitals	27	15	811,091	16.56
Rendezvous ECPR	5 mobile teams leaving from current ECPR capable hospitals	27	15	2,175,096	22.42
Pre-hospital ECPR	1 mobile team + 5 current ECPR capable hospitals	N/A	22	3,851,727	42.71

The three measures are: (1) Population that has access to ECPR within 60 min (2) the average survival probability assuming a threshold of 60 min from arrest to ECMO flow [23]
