Know the Signs of Secondary Drowning

Unlike typical drowning, secondary drowning can happen hours after an individual is out of the water. When water gets into the lungs, it can cause excess fluid buildup called a pulmonary edema. This can lead to inflammation, which makes the transfer of oxygen to carbon dioxide difficult, causing breathing troubles and in severe cases, even death. The warning signs of secondary drowning include blue lips, pale skin, persistent coughing, shallow breathing, sleepiness, and vomiting. This type of drowning is less common, but occurs more frequently in children. Enrolling children in swimming lessons lets them get comfortable being in water and can help reduce the chances that they go under and take in large amounts of water. Always monitor children closely both during and after swimming.
