Indicator of cardiac arrest requiring cardiopulmonary resuscitation (i.e. at least two minutes of chest compressions). Cardiac arrest is a condition in which the heart suddenly and unexpectedly stops beating

GENERAL/TBI: Choose one. This element is recommended for pediatric studies. Second insults may aggravate processes of secondary damage in a brain already rendered vulnerable by the primary injury. The main physiologic insults relevant to TBI are hypotension, hyper- or hypothermia, hypoxia, and hypocapnia due to hyperventilation. The adverse effect of the occurrence of such insults both pre- and in-hospital is well established. Second insults are commonly defined by threshold values but these values are not well established in pediatrics. Based on the available data for pediatric TBI , thresholds of 80-180 mg/dL for glucose are recommended. A threshold for hemoglobin is more difficult to define given emerging data on the lower limit of hemoglobin safely tolerated by critically ill children in general and the variable effect of blood transfusion in children with severe TBI specifically.
