Which of the following could be a sign of troubled breathing?

Gasping for breath is a clear indicator of troubled breathing. It signifies that the person is not receiving enough air, which can lead to a critical situation requiring immediate attention. Gasping can occur due to a variety of factors, such as an obstruction in the airway, respiratory distress, or panic, and points to a malfunction in the body’s normal respiratory function.

Conversely, consistent coughing can be a sign of various conditions, but it does not necessarily indicate that someone is in immediate distress. A normal breathing rate indicates that the respiratory system is functioning well, and feeling relaxed and calm further suggests that a person is not experiencing any breathing difficulties. These other options do not demonstrate signs of immediate respiratory distress like gasping does. Understanding these distinctions is crucial for lifeguards in identifying when someone may need urgent medical help.
