Question

Quizplus · Accepted Answer

Dyspnea, orthopnea, and barrel chest are classic signs of emphysema, a type of chronic obstructive pulmonary disease (COPD). Chronic bronchitis may also present with dyspnea and cough, but is less likely to have a barrel chest. Upper respiratory infection and pneumonia may cause dyspnea, but are less likely to lead to a chronic and progressive condition like emphysema. Dyspnea (shortness of breath) and orthopnea (difficulty breathing when laying down) are common symptoms of emphysema, a type of chronic obstructive pulmonary disease (COPD). A barrel chest is also a physical finding commonly associated with emphysema due to the increased lung volume and flattened diaphragm. Chronic bronchitis may also cause dyspnea and barrel chest, but typically does not cause orthopnea. Upper respiratory infection and pneumonia may cause dyspnea but are not typically associated with a barrel chest.
