Question: 1 / 400

What does the Kussmaul sign indicate?

Decreased heart rate

Severely increased pressure in the chest or around the heart

The Kussmaul sign is characterized by a paradoxical rise in jugular venous pressure (JVP) with inspiration, which is typically not expected. This phenomenon occurs due to impaired filling of the right ventricle, often seen in conditions such as constrictive pericarditis or restrictive cardiomyopathy. When the Kussmaul sign is present, it suggests that there is severely increased pressure in the chest or around the heart, leading to decreased right ventricular compliance.

This condition indicates that the heart is unable to accommodate the increased venous return that occurs with inhalation, and thus reflects underlying pathology related to the heart's ability to function effectively. Recognizing this sign is crucial for EMTs and other healthcare providers, as it helps in identifying potential cardiac issues that may require immediate intervention.
