Why is the fifth stage of drowning considered dangerous?

The fifth stage of drowning is considered dangerous primarily because it can lead to non-reversible damage. This stage represents a point where the victim has already undergone significant physiological stress and potential trauma from lack of oxygen. As the body is deprived of oxygen, critical organs, especially the brain, may begin to suffer irreversible damage due to oxygen deprivation, which can lead to long-term complications or even death. Understanding this stage emphasizes the importance of prompt and effective rescue techniques, as well as the need for appropriate medical intervention to mitigate long-term consequences following a drowning incident. This understanding underscores the life-saving role lifeguards play in preventing progression to this critical stage.
