Cardiac arrest & resuscitation
Foreign body airway obstruction resulting in out-of-hospital cardiac arrest in Denmark – Incidence, survival and interventions
Authors' conclusion
FBAO-related OHCA was rare but has a higher initial survival rate than non-FBAO related OHCA, with a considerable proportion of patients achieving return of spontaneous circulation upon arrival of the emergency medical service personnel. No definitive associations were established between survival and specific interventions performed by bystanders or EMS personnel.
