Question: 1 / 400

What does the term "secondary drowning" refer to?

A condition causing immediate respiratory failure

An incident occurring 24 hours after swimming

A condition where water is inhaled into the lungs, causing respiratory distress after leaving the water

The term "secondary drowning" refers to a situation where water is inhaled into the lungs while a person is submerged, leading to respiratory distress that may manifest after they have exited the water. This can happen because the inhaled water can cause irritation and swelling of the lungs (pulmonary edema), or it can interfere with the lungs' ability to exchange oxygen and carbon dioxide effectively. Unlike immediate drowning, where a person cannot breathe and suffers a rapid loss of consciousness and respiratory function, secondary drowning can present symptoms hours later, making it crucial for lifeguards and bystanders to monitor individuals after a near-drowning incident. Recognizing secondary drowning symptoms and understanding that they can develop post-exit from the water emphasizes the importance of vigilance in water safety and post-incident care.
