Knowra Opioid overdose Opioid overdose Opioid overdose occurs when opioid exposure causes dangerous toxic effects, especially slowed or stopped breathing. It can lead to brain injury and death without prompt treatment.
Opioid receptors : Cell-surface receptors that respond to endogenous opioids and opioid drugs, altering pain signaling and other functions. Opioids activate these receptors in brainstem circuits that regulate breathing.
Overdose first aid : Immediate actions to support someone experiencing a suspected drug overdose while emergency help is obtained. Prompt assistance can sustain breathing and circulation until advanced care arrives.
Opioid : A substance that activates opioid receptors, including natural, semisynthetic, and synthetic drugs used medically or nonmedically. Opioid overdose is a toxic outcome of exposure to this broad drug class.
Opioid withdrawal : A group of symptoms that can occur when opioid use is reduced or stopped after physical dependence develops. Withdrawal is usually distressing rather than the breathing-threatening syndrome of overdose.
Respiratory depression : Abnormally slow or shallow breathing that reduces oxygen delivery and can cause carbon dioxide buildup. This is the principal life-threatening effect of opioid toxicity.
Naloxone administration : The use of naloxone by nasal spray, injection, or other approved route to reverse opioid effects. Repeated doses may be needed if breathing does not recover or symptoms return.
Opioid pharmacology : The study of how opioid drugs act in the body, including their effects, metabolism, and interactions. Drug potency, duration, and interactions shape overdose severity and recurrence.
Sedative overdose : Toxic exposure to sedative drugs that can impair consciousness, coordination, and breathing. Sedatives can resemble or accompany opioid toxicity, but naloxone does not reverse their effects.
Naloxone : A medication that rapidly displaces opioids from receptors and can temporarily reverse opioid overdose. It can restore breathing, but its effects may wear off before the opioid does.
Bag-valve-mask ventilation : Manual ventilation using a self-inflating bag and mask to move air into a person's lungs. Ventilation supports oxygenation when opioid-related breathing is inadequate.
