Advanced age is not an independent predictor of survival.Asystole for 20 minutes is generally considered non-survivable if asystole -> always check leads, gain settings and connections

Survival to discharge from out-of-hospital arrest (OOHA) is minimal if the initial rhythm on arrival in ED is asystole or agonal.Survival from cardiac arrest is highly dependent on time to defibrillation and return of spontaneous circulation (ROSC) unless a primary reversible cause is present.However, selected patients potentially have good outcomes with prolonged, aggressive resuscitation (see ‘when not to stop’) Always maintain initial resuscitation efforts until adequate information is available to make the call to discontinue.The decision is best made by the Team Leader in consultation with other team members.The decision to stop CPR should be tailored according to the specifics of the individual case and is based on clinical judgement.Most resuscitation attempts are unsuccessful - we need to know when to stop.
