What is the recommended method to retrieve an unconscious diver?

Using a rescue buoy or flotation device to assist in retrieving an unconscious diver is the recommended method because it enhances the safety and effectiveness of the rescue operation. When a diver is unconscious, their ability to help themselves is compromised, and it can be very dangerous to attempt to pull them up without proper buoyancy support. A flotation device can provide extra buoyancy, making it easier to manage the weight of the diver and reduce the risk of injury to both the rescuer and the unconscious diver.

This method allows the rescuer to keep the unconscious diver afloat while ensuring they have their own safety maintained. It also enables a controlled ascent, which is crucial for avoiding decompression sickness, as rapid ascents can lead to serious injuries.

In contrast, pulling a diver by their wetsuit can be risky, as it may not provide a secure grip, leading to potential harm to the diver. Leaving an unconscious diver until they regain consciousness poses significant danger to their health, as they may be submerged, leading to drowning or further complications. Taking an unconscious diver to the surface immediately without proper safety measures can also lead to serious risks, like rapid ascent injuries and difficulties in managing the unconscious diver effectively.
