Effect of Hemoglobin Levels on Cases of Cardiac Arrest

      Cardiac arrest (CA) is currently a life-threatening condition. Preventative measures to reduce mortality in patients with CA have led to the analysis of hemoglobin (Hb) levels directly after the CA. Several studies have shown a positive link between Hb levels shortly after a CA and a better outcome for the patient.

      Furthermore, there is evidence to indicate a significant relation between higher Hb levels after CA and the return of spontaneous circulation (in conjunction with a good neurologic outcome within several hours after the CA, in addition to survival to hospital discharge).

      and his retrospective cohort study in which the researchers concluded that the minimum required Hb concentration for a favorable outcome was 8.6 to 9.0 g/100 ml. The purpose of this research is to understand whether Hb concentration could be used as a possible mortality indicator.
