What are the two types of blood pressure?

• A. Systolic and diastolic
• B. Cardiac and vascular
• C. Venous and arterial
• D. Mean and pulse pressure

Answer: (A)

Blood pressure is expressed as two numbers that reflect pressure in the arteries during different parts of the heartbeat. The top number is the systolic pressure—the peak pressure when the heart contracts and pushes blood into the arteries. The bottom number is the diastolic pressure—the lower pressure when the heart is relaxed and the ventricles fill. This pair captures the arterial pressure throughout the cardiac cycle and is what clinicians use to assess blood pressure status. The other terms aren’t the standard pair used to describe a single blood pressure reading. Cardiac and vascular describe parts of the circulatory system, not two readings. Venous and arterial refer to types of vessels, not measurement values. Mean and pulse pressure are derived quantities: mean arterial pressure is an average pressure over the cycle, and pulse pressure is the difference between systolic and diastolic pressures.
