Which of the following is a sign of opioid overdose?

The sign indicating an opioid overdose is characterized by slow, shallow, or even no breathing. Opioids have a significant depressant effect on the central nervous system, which can lead to respiratory depression. This means that the person may breathe less frequently, take very shallow breaths, or stop breathing altogether. This is a critical and life-threatening condition that necessitates immediate medical attention, as insufficient breathing can result in a lack of oxygen to the brain and lead to death if not promptly addressed.

Recognizing this symptom is crucial in providing timely assistance, such as initiating rescue breathing or utilizing naloxone, an opioid antagonist that can reverse the effects of an overdose. Understanding this symptom can save lives and is a key component of basic life support protocols.
