Secondary drowning is marked by symptoms resulting from a serious near-drowning incident. It does not happen after a child swallows a small amount of water. Symptoms occur from a buildup of fluid in the alveoli of the lungs as part of an inflammatory response to the near-drowning event, not from the fluid that was inhaled during submersion. Secondary drowning can occur in both adults and children, but more commonly affects children. It can be difficult to recognize because the person appears to be fine shortly after the incident.
Symptoms of secondary drowning may begin several hours afterwards and include:
- Development of a cough or chest pain
- Extreme fatigue in the hours after a near-drowning incident
- Poor skin coloration
- The rapidness with which the near-drowning victim is breathing
- How the abdominal, chest and neck muscles are being used
- The victim’s cognition, including changes to his or her ability to think or speak
