  • *Values are expressed as the mean (SD) final ranking assigned during round 4 of the process, with a lower value indicating a higher priority.

  • OHCA, out-of-hospital cardiac arrest; PHEA, prehospital emergency anaesthetic; POCUS, point-of-care ultrasound; ROSC, return of spontaneous circulation.
