Which pulse is typically eliminated by light pressure?

Which pulse is typically eliminated by light pressure?

• A. Jugular
• B. Carotid
• C. Both
• D. Neither

Answer: (A)

The key idea is differentiating venous pulsations from arterial pulsations in the neck. The jugular venous pulse is a venous signal that can be temporarily eliminated with light pressure over the neck because you compress the vein and collapse the venous column. The carotid pulse, on the other hand, is an arterial pulsation and remains detectable with gentle neck pressure; only firmer compression would dampen it, which isn’t the technique used here. So, with light neck pressure, the pulsation you typically lose is the jugular venous pulse, while the carotid pulse persists. This distinction helps clinicians tell venous from arterial pulsations during a physical exam.
