A patient experiences a significant drop in systolic blood pressure during inspiration. What condition is MOST closely associated with this finding?
Understand the Problem
The question describes a clinical scenario where a patient's systolic blood pressure drops significantly during inspiration. This phenomenon is known as pulsus paradoxus. The question asks us to identify the condition most closely associated with pulsus paradoxus from the given options.
Answer
Cardiac tamponade.
The condition most closely associated with a significant drop in systolic blood pressure during inspiration (pulsus paradoxus) is cardiac tamponade.
Answer for screen readers
The condition most closely associated with a significant drop in systolic blood pressure during inspiration (pulsus paradoxus) is cardiac tamponade.
More Information
Pulsus paradoxus is defined as a decrease in systolic blood pressure by more than 10 mm Hg during inspiration. While most closely associated with cardiac tamponade, it can also be seen in other conditions such as pericardial effusion and asthma.
Tips
Pulsus paradoxus is not exclusive to cardiac tamponade. Other conditions, especially those affecting the lungs, can also cause this finding.
