HESI EMT-Basic Exit - Exam Topics Sample Questions

Blood pressure can be expressed as which of the following?

Correct Answer:
cardiac output x peripheral vascular resistance


blood pressure (bp) is a critical physiological parameter that indicates the force of circulating blood on the walls of blood vessels. it is fundamentally determined by two main factors: cardiac output and peripheral vascular resistance.

cardiac output is the volume of blood the heart pumps per minute. it is calculated as the product of stroke volume (the amount of blood pumped by the heart with each beat) and heart rate (the number of heartbeats per minute). thus, cardiac output can be expressed as: \[ \text{cardiac output} = \text{stroke volume} \times \text{heart rate} \]

on the other hand, peripheral vascular resistance refers to the resistance that blood vessels provide against the flow of blood. this resistance is influenced by various factors, including the diameter and elasticity of the blood vessels, as well as the viscosity of the blood.

the relationship between blood pressure, cardiac output, and peripheral vascular resistance can be encapsulated in the formula: \[ \text{blood pressure} = \text{cardiac output} \times \text{peripheral vascular resistance} \] this equation underscores how changes in either cardiac output or peripheral vascular resistance can impact blood pressure.

for instance, an increase in cardiac output, say due to increased heart rate or stroke volume, typically elevates blood pressure, assuming peripheral resistance remains constant. similarly, an increase in peripheral vascular resistance, perhaps due to narrowing of the blood vessels (vasoconstriction), also tends to raise blood pressure if cardiac output is unchanged.

conversely, a decrease in cardiac output or a reduction in peripheral vascular resistance (e.g., through vasodilation, where blood vessels widen) generally results in a decrease in blood pressure. this dynamic interaction between cardiac output, peripheral vascular resistance, and blood pressure is a fundamental concept in understanding cardiovascular health and is crucial for managing conditions like hypertension.

in summary, the expression of blood pressure as the product of cardiac output and peripheral vascular resistance encapsulates a core physiological relationship, reflecting how the cardiovascular system adapts to various physiological and pathological conditions to maintain homeostasis.
