Which considerations should be included in the first aid measures for an unconscious scuba diver?

The primary focus when administering first aid to an unconscious scuba diver involves serious diving-related injuries that can arise from underwater activities. Drowning is a critical concern because unconsciousness can lead to the loss of the ability to breathe, exposing the diver to the risk of asphyxiation. Air embolism is another vital consideration, as it occurs when gas bubbles enter the bloodstream, potentially causing life-threatening complications if the diver ascended too quickly or held their breath while ascending. Decompression sickness, commonly known as "the bends," also needs to be addressed, as it can result from rapid changes in pressure and can have severe health implications if not treated promptly.

Incorporating these elements into first aid measures ensures that the responder is prepared to handle the most immediate and hazardous threats to an unconscious diver's life, emphasizing the importance of prioritizing interventions that address critical injury types commonly associated with scuba diving incidents.
