Orthopnea is best described as which symptom?

Explanation:
Orthopnea is shortness of breath that occurs when lying flat. When a person lies down, venous return to the heart increases and the lungs have less space to expand, which can worsen pulmonary congestion from heart failure. This makes breathing feel harder until the person sits up or propped upright, often with pillows. This symptom is a classic clue to left-sided heart failure or fluid overload. It’s different from SOB that occurs when standing, a chronic cough, or cyanosis at rest, which point to other problems.
