What characterizes the fourth stage of drowning?

The fourth stage of drowning is characterized by hypoxic convulsions, which occur as the body becomes critically deprived of oxygen. During drowning, as the respiratory system fails and oxygen levels drop, the brain reacts by initiating convulsive movements. This is a life-threatening response that indicates severe physiological distress, highlighting the urgency of immediate rescue efforts.

Understanding this stage is crucial for lifeguards and responders, as recognizing these convulsions can help them quickly assess the severity of the situation and respond appropriately to prevent further injury and facilitate rescue. The presence of hypoxic convulsions signifies that the individual is in a critical condition where every second counts, emphasizing the importance of rapid intervention and potential resuscitation measures.
