Figure 1From: A systematic review of neuroprotective strategies after cardiac arrest: from bench to bedside (part II-comprehensive protection)Neuroprotective mechanisms of gas-mediated approaches after resuscitation from cardiac arrest. Hydrogen sulfide (H2S), hyperbaric oxygen (HBO) and hydrogen gas (H2) exert anti-oxidant, anti-inflammation and anti-apoptosis effects through regulation of variable signaling pathways. Such comprehensive brain protection leads to improved outcomes in the setting of global brain injury associated with cardiac arrest.Back to article page
