Final answer:
When assisting a panicked diver, prioritize bringing them to stable ground before performing CPR. Drowning victims may not be able to call for help due to a blocked airway, and divers must be cautious of rapid ascents to prevent decompression sickness. Always act promptly in emergency situations and seek help if needed.
Step-by-step explanation:
The most important rule when assisting a panicked diver is to ensure their immediate safety by bringing them to stable ground as quickly as possible before administering any emergency procedures like CPR. It's a common misconception that CPR should be started immediately, even before the person is removed from the water; however, it is crucial to understand that CPR is ineffective in the water and that the drowning person must be on stable ground for the procedure to work.
Many people also mistakenly believe that a drowning person will be loud and attention-grabbing, but in reality, they are often unable to shout or wave for help because of a muscular spasm that seals their airway, so vigilance is key. When it comes to diving, always pay attention to 'no diving' signs as diving in shallow water can lead to severe injuries. Scuba divers must also be aware of the risks associated with the ascent to the surface, as rapid ascents can cause decompression sickness (DCS), and preventative measures such as slow ascents or decompression stops are advised to avoid it.
If you come across a person who needs help, it's important to be proactive, despite the bystander effect, and ensure they receive the necessary assistance. If you're unable to provide help, you should immediately notify someone who can.
