Post-immersion collapse, also known as "shallow water blackout," is a sudden loss of consciousness that can occur after a person has been freediving or breath-holding underwater. It is often caused by hyperventilation before diving, which can lead to a decrease in blood oxygen levels without the diver realizing it. This can result in a blackout, which can be dangerous or fatal if it happens while the person is still underwater.
