In the decompensation stage of shock, which description best matches pulse pressure?

Pulse pressure is the difference between systolic and diastolic pressures, and it reflects how much blood is being ejected with each beat (stroke volume) and how the vessels are responding to blood flow. In the decompensation stage of shock, the heart is pumping less effectively and the vessels remain constricted. This causes the systolic pressure to fall as the stroke volume drops, while diastolic pressure tends to stay higher or rise due to vasoconstriction. The combination of a lower systolic value with a relatively higher diastolic value narrows the pulse pressure. As shock progresses further, the pulse pressure can become very small or even disappear. This narrowing is a hallmark of decompensation, distinguishing it from conditions that widen pulse pressure, where the pulse pressure would be larger because systolic pressure remains high or diastolic pressure falls.
