Question

Quizplus · Accepted Answer

Hoover's sign is a unique breathing pattern commonly seen in COPD patients in which the lower lateral margins of the chest wall pull inward with each inspiration. This is due to increased use of accessory muscles of respiration to help with breathing, leading to retractions of the chest wall during inspiration. Homans' sign is a sign of deep vein thrombosis, respiratory alternans refers to a pattern of alternate breathing between the two lungs, and respiratory retractions are a more general term for any inward pulling or retraction of the chest wall during breathing.
