What is the main hemodynamic parameter that measures preload?
Systolic Blood Pressure.
Mean Arterial Blood Pressure.
Central Venous Pressure (CVP).
Systemic Vascular Resistance.
The Correct Answer is C
Choice A reason: Systolic Blood Pressure is not a direct measure of preload; it indicates the pressure in the arteries during the contraction of the heart muscles.
Choice B reason: Mean Arterial Blood Pressure is an average blood pressure in an individual during a single cardiac cycle, but it does not specifically measure preload.
Choice C reason: Central Venous Pressure (CVP) is a direct measure of the blood volume returning to the heart and the ability of the heart to pump the blood into the arterial system, making it a key indicator of preload.
Choice D reason: Systemic Vascular Resistance refers to the resistance to blood flow offered by all of the systemic vasculature, excluding the pulmonary vasculature, and is not a measure of preload.
