Diagnosis of brain injury involves neurological examination, EEG, brain imaging and/or biomarker evaluation (such as S100B and NSE). [6] For out-of-hospital cardiac arrest, brain injury is the cause of death in most patients who undergo ROSC but ultimately die.
Cardiac arrest (also known as sudden cardiac arrest [SCA] [11]) is when the heart suddenly and unexpectedly stops beating. [ 12 ] [ 1 ] When the heart stops beating, blood cannot properly circulate around the body and the blood flow to the brain and other organs is decreased.
Global brain ischemia occurs when blood flow to the brain is halted or drastically reduced. This is commonly caused by cardiac arrest. If sufficient circulation is restored within a short period of time, symptoms may be transient. However, if a significant amount of time passes before restoration, brain damage may be permanent.

With the advent of these strategies, cardiac arrest came to be called clinical death rather than simply death, to reflect the possibility of post-arrest resuscitation. At the onset of clinical death, consciousness is lost within several seconds, and in dogs, measurable brain activity has been measured to stop within 20 to 40 seconds. [2]
This is done in an attempt to reduce the risk of tissue injury following lack of blood flow. [2] Periods of poor blood flow may be due to cardiac arrest or the blockage of an artery by a clot as in the case of a stroke. [3] Targeted temperature management improves survival and brain function following resuscitation from cardiac arrest. [4]
Traumatic cardiac arrest is a complex form of cardiac arrest often derailing from advanced cardiac life support in the sense that the emergency team must first establish the cause of the traumatic arrest and reverse these effects, for example hypovolemia and haemorrhagic shock due to a penetrating injury.
