Which vital sign may indicate shock in patients over 65 years of age?

In patients over 65 years of age, a systolic blood pressure of less than 110 can be a significant indicator of shock. This demographic is more susceptible to changes in blood pressure due to a host of factors including comorbidities, the effects of aging on cardiovascular function, and medication effects. When systolic blood pressure drops below this threshold, it may suggest inadequate perfusion and stable blood flow to vital organs, which is a critical concern in assessing shock.

In older adults, vital signs can sometimes present differently than in younger populations, making the standard thresholds less reliable. Therefore, considering systolic blood pressure specifically can help healthcare providers identify potential shock even when other signs might not be as pronounced. In this population, early recognition is crucial for effective intervention.
