Which vital sign is an indication of hypoperfusion?

Hypoperfusion, which refers to inadequate blood flow to the tissues, is commonly indicated by hypotension. Blood pressure that is significantly lower than normal (hypotension) signifies that the body's organs and tissues may not be receiving sufficient oxygen and nutrients, leading to potential organ failure if not addressed promptly.

Wide pulse pressures, while sometimes observed in certain conditions, do not specifically indicate hypoperfusion; in fact, they can occur in situations such as increased intracranial pressure or arterial stiffness. Bradycardia, or a slow heart rate, may not directly relate to blood flow adequacy since it can be a response to various situations, including increased vagal tone or certain medications. Warm, dry skin typically suggests adequate perfusion and is more characteristic of conditions like heat exposure or septic shock, rather than hypoperfusion.

Thus, when considering a vital sign indicative of hypoperfusion, hypotension is the most relevant choice, as it directly relates to the reduced capacity to maintain adequate blood flow and pressure to vital organs.
