Quizplus · Accepted Answer

Chronic hypoxemia can lead to fatigue and lethargy, as the body struggles to compensate for the lack of oxygen. Bradycardia (slow heart rate) can be seen in severe cases, but is not necessarily a definitive sign. Shortening of the nail beds (clubbing) and peripheral edema are more indicative of chronic respiratory failure or cor pulmonale, which can be a sequelae of chronic obstructive pulmonary disease (COPD), but are not specific for chronic hypoxemia.
