Diving First Aid Practice Test 2025 – Complete Exam Preparation

The goal of providing the highest concentration of oxygen to an injured diver is primarily to facilitate inert gas washout and improve oxygen delivery. When a diver experiences problems like decompression sickness or arterial gas embolism, the presence of inert gases dissolved in their tissues needs to be addressed. Administering high concentrations of oxygen helps to wash out these gases from the body more effectively and rapidly, allowing them to be exhaled more efficiently.

Additionally, providing oxygen boosts the availability of oxygen to the injured tissues, which is crucial for recovery and prevents further complications associated with hypoxia. This strategy is vital in managing diving-related injuries and serves to enhance the body's natural healing processes.

Achieving this objective is essential for ensuring that the diver receives the best possible chance of recovery and minimizes the risk of serious, long-term complications. While other results, such as a return to consciousness or immediate medical evacuation, are important aspects of diver care, they are not the primary reason for delivering high concentrations of oxygen in the context of treating inert gas-related injuries.
