Blood pressure systolic diastolic

What is systolic blood pressure?

The pressure in arteries during heartbeats. It reflects the force exerted by blood when the heart contracts.

What is diastolic blood pressure?

The pressure in arteries between heartbeats. It indicates the resistance in blood vessels when the heart is relaxed.

True or false: Systolic pressure is always higher than diastolic pressure.

True, because systolic pressure measures the peak pressure during heart contraction.

Difference between systolic and diastolic pressure

Systolic is the maximum pressure during heartbeats, while diastolic is the minimum pressure when the heart relaxes.

Fill in the blank: Normal blood pressure is often defined as _____ mmHg.

120/80 mmHg.

What does a blood pressure reading of 140/90 mmHg indicate?

This reading indicates hypertension, as it exceeds the normal range.

Question: What is considered hypertension?

Hypertension is generally defined as a consistent blood pressure of 130/80 mmHg or higher.

What factors affect blood pressure?

Factors include age, weight, diet, physical activity, and genetics.

True or false: Blood pressure fluctuates throughout the day.

True, because it can vary based on activity levels, stress, and other factors.

What is the formula for calculating mean arterial pressure (MAP)?

MAP is calculated as $\displaystyle MAP = DBP + \frac{1}{3}(SBP - DBP)$.

True or false: High diastolic pressure is less concerning than high systolic pressure.

False, because high diastolic pressure can also indicate health issues.

What is a common way to measure blood pressure?

A sphygmomanometer is commonly used to measure blood pressure non-invasively.

Fill in the blank: A reading of 90/60 mmHg indicates _____ blood pressure.

Low blood pressure, or hypotension.

Question: How can lifestyle affect blood pressure?

Healthy diets, regular exercise, and stress management can lower blood pressure.
