Of 100 patients suffering out-of-hospital cardiac arrest (OHCA), ~30–40 are successfully resuscitated in the field with return of spontaneous circulation and reach the hospital. Of those 30–40, ~5–10 survive to hospital discharge (5–10% overall survival).¹⁷⁶ A better survival is seen in patients whose initial rhythm is VF/VT (22% survival to discharge). In patients with VF, the survival decreases by 7–10% for each minute of delay to defibrillation. The prognosis is very poor in patients with non-shockable rhythm: survival to hospital discharge 10% for PEA and 2% for asystole. Some patients with non-shockable rhythm develop VT/VF during the course of resuscitation, but they should still be considered as non-shockable rhythm for the purposes of prognosis and therapy.¹⁷⁷
