Differentiating Sepsis, Severe Sepsis, and Septic Shock The sepsis 3 criteria simplified the historical subclassifications of severe sepsis and septic shock into a more linear progression. Sepsis represents a life-threatening organ dysfunction caused by a dysregulated host response to infection, and accurate identification is critical for timely intervention.

The respiratory component assesses the partial pressure of oxygen (PaO2) to fraction of inspired oxygen (FiO2) ratio, reflecting oxygenation efficiency. The qSOFA incorporates three simple bedside parameters: respiratory rate of 22 breaths per minute or greater, altered mentation, and systolic blood pressure of 100 mm Hg or less.
This objective assessment provides a clear threshold for clinicians to distinguish sepsis from less severe infections. Key Components of the SOFA Assessment Each component of the SOFA score is scored from 0 to 4, allowing for a nuanced evaluation of physiological derangement.
Using the Quick SOFA Checklist to Apply Sepsis 3 Criteria
Sepsis is defined by the SOFA score increase, while septic shock is identified by sepsis with persisting hypotension requiring vasopressors to maintain a mean arterial pressure of 65 mm Hg or greater and with serum lactate level greater than 2 mmol/L despite adequate volume resuscitation. Moving away from a systemic inflammatory response syndrome (SIRS) paradigm, this approach focuses on the presence of suspected infection coupled with acute organ dysfunction.
