How is dyspnea defined?

Dyspnea is defined as difficulty breathing. This term encompasses a range of breathing difficulties, including the sensation of not getting enough air or the feeling of breathlessness, whether acute or chronic. It can be caused by various medical conditions, including respiratory or cardiac issues. This symptom can significantly affect a person's quality of life and is an important indicator that healthcare professionals evaluate when assessing a patient’s respiratory health.

While increased breathing rate can occur with dyspnea, it is not synonymous with the term itself. Likewise, chronic coughing and shortness of breath due to anxiety can be associated with respiratory issues, but they describe distinct conditions or symptoms rather than defining dyspnea directly. Hence, the choice indicating difficulty breathing correctly encapsulates the essence of dyspnea.
