A shallow water blackout is a loss of consciousness caused by cerebral hypoxia. It typically happens at the end of a breath-hold dive in shallow water of less than sixteen feet. Victims are commonly practitioners of the breath-hold diving and are strong swimmers. Several drownings occur among swimmers who black out underwater as they are free diving or swimming laps while holding their breath.
Though the mechanism is well understood it is not common knowledge among breath-hold swimmers and divers.
