Opioid-induced respiratory depression

Opioid-induced respiratory depression is a potentially fatal adverse effect and medical emergency characterized by significant central nervous system and ventilatory suppression following exposure to opioid agonists

Opioid-induced respiratory depression is a potentially fatal adverse effect and medical emergency characterized by significant central nervous system and ventilatory suppression following exposure to opioid agonists Clinically, affected patients exhibit hypoventilation characterized by markedly decreased respiratory rate, shallow breathing, periodic apnea, and progressive central nervous system sedation, which leads to severe hypoxemia, respiratory acidosis, and potential cardiac arrest if left ...

Pathophysiologically, it occurs when opioids activate mu-opioid receptors within respiratory control networks of the brainstem, specifically dampening neural rhythmogenesis in the pre-Bötzinger complex and blunting central and peripheral chemoreceptor sensitivity to rising hypercapnia and hypoxia
