Final answer:
In cases of opioid overdose, if a person is not breathing or has no heartbeat, start CPR immediately and use naloxone to reverse the overdose. For drowning, the individual must be brought to stable ground first before administering CPR.
Step-by-step explanation:
The question is whether to administer CPR first or use naloxone (Narcan) when dealing with a potential opioid overdose. If someone is not breathing or their heartbeat is not detectable, it is essential to begin CPR immediately. Opioids can cause breathing to slow down or stop, which can lead to death. Naloxone is a medication designed to rapidly reverse an opioid overdose by blocking the effects of opioids and can restore normal breathing in a person whose breathing has slowed or stopped as a result of taking opioids. When responding to an opioid overdose, it is critical to call emergency services right away for assistance.
When dealing with a drowning incident, removing the person from the water is the first step. Once on stable ground, you should start CPR if the person is not breathing or does not have a pulse. Time is crucial in both situations; starting CPR as quickly as possible greatly increases the chances of survival. Administering CPR can provide essential support until emergency medical professionals arrive. In cases of cold-water drowning, there have been instances where recovery was possible even after extended periods due to a protective effect of the cold on brain activity.
