Which of the following best describes the period of release in blood pressure measurement?

• A. Systolic blood pressure
• B. Diastolic blood pressure
• C. Average blood pressure
• D. Post-exercise blood pressure

Answer: (B)

The term "period of release" in blood pressure measurement refers specifically to the diastolic blood pressure. Diastolic blood pressure is the measurement taken when the heart is at rest between beats, allowing the chambers of the heart to fill with blood. This indicates the lowest pressure within the arteries during the cardiac cycle. During this phase, the heart is not actively pumping blood, and the pressure in the arteries is at its minimum. This is critical for assessing the overall cardiovascular health of an individual, as it helps indicate how well the arteries are handling blood flow at rest. In contrast, systolic blood pressure, which measures the pressure when the heart is contracting and pumping blood, does not represent the period of release. Average blood pressure represents a calculated mean of systolic and diastolic pressures, and post-exercise blood pressure refers to the changes occurring in blood pressure following physical activity, which does not pertain to the resting state measured as diastolic. Therefore, the correct identification of the period of release in blood pressure measurement is best explained through diastolic blood pressure.
