What is one of the four main actions to consider for first aid in diving accidents?

Maintaining basic life support is a crucial action in first aid for diving accidents because it ensures that the diver’s vital functions are stabilized until emergency medical services can arrive. Basic life support encompasses critical interventions such as checking for responsiveness, ensuring clear airways, monitoring breathing, and providing adequate circulation. These steps help to keep the diver’s body functioning and can prevent further harm, especially in situations where there could be oxygen deprivation or other life-threatening conditions following a diving incident.

The other options, while potentially relevant in different contexts, do not constitute the primary immediate action needed when dealing with a diving accident. For instance, calling for transportation is essential but occurs after ensuring the immediate life support needs are addressed. Similarly, while CPR may be necessary in some cases, it should only be performed if the diver is unresponsive and not breathing, making it a specific response rather than a basic support action. Evaluating diving equipment, while important for understanding the cause of the accident, does not address the immediate needs of the individual in distress.
