A present carotid pulse indicates a systolic blood pressure of at least how many mmHg?

• A. 50 mmHg
• B. 60 mmHg
• C. 70 mmHg
• D. 80 mmHg

Answer: (B)

Feeling the carotid pulse means the heart is generating enough pressure to push blood through a large central artery, which happens when systolic blood pressure is about sixty millimeters of mercury or higher. In the field, you estimate SBP by palpating pulses because you may not have a cuff or stethoscope. The carotid artery is easier to feel at a lower pressure, so a palpable carotid pulse corresponds to roughly the 60 mmHg mark. If you can’t feel a carotid pulse, the SBP is likely lower than that. For comparison, a palpable femoral pulse typically occurs around seventy and a palpable radial pulse around eighty, so those thresholds are higher than what you’d detect in the carotid.
