The correct interpretation of the qSOFA criteria identifies hypotension as a blood pressure reading of less than or equal to 90 mmHg. Specifically, in the context of the qSOFA assessment, hypotension is defined in terms of systolic blood pressure. A reading at or below this threshold can indicate a potential for sepsis and is a critical factor when evaluating a patient's condition.

In clinical practice, maintaining an adequate blood pressure is essential for ensuring adequate perfusion to organs and tissues; thus, understanding these thresholds helps healthcare providers recognize patients who may be at risk of severe illness or require more intensive monitoring and intervention. The value of 90 mmHg is set as a key indicator to prompt further evaluation and possible treatment strategies in critical care settings or when assessing for sepsis.
