A common symptom of low cardiac output is low blood pressure. When the heart is unable to pump an adequate volume of blood to meet the body's needs, the result is often a decrease in blood pressure. Cardiac output is critical for maintaining adequate circulation, ensuring that all organs receive sufficient oxygen and nutrients. When cardiac output is low, it can lead to insufficient blood flow to vital organs, which typically manifests as hypotension or low blood pressure.

In contrast, high blood pressure is generally associated with conditions where there is increased resistance or volume in the circulatory system, not with low cardiac output. Being alert and oriented tends to indicate adequate perfusion and oxygenation to the brain and body, which wouldn't be the case if cardiac output were low. Increased perfusion of organs would suggest that blood flow is adequate or improved, which contradicts the concept of low cardiac output. Thus, low blood pressure accurately reflects the state of low cardiac output and its impact on the body’s circulation.
