qSOFA (Quick SOFA) Score Calculator

Calculate qSOFA quickly to flag possible sepsis risk using respiration rate, blood pressure, and mental status.

Calculator

Results

qSOFA Score: 0

Data Source and Methodology

The qSOFA score is based on clinical guidelines for assessing the risk of sepsis. All calculations rely strictly on these established medical standards. Source.

The Formula Explained

qSOFA = (Respiratory Rate ≥ 22) + (Altered Mental Status) + (Systolic Blood Pressure ≤ 100 mmHg)

Glossary of Variables

  • Respiratory Rate: Number of breaths per minute.
  • Altered Mental Status: Changes in consciousness or awareness.
  • Systolic Blood Pressure: The pressure in blood vessels when the heart beats.

How It Works: A Step-by-Step Example

For a patient with a respiratory rate of 24, altered mental status, and systolic blood pressure of 95 mmHg, the qSOFA score would be 3, indicating a high risk of sepsis.

Frequently Asked Questions (FAQ)

What is the qSOFA score?

The qSOFA score is a quick assessment tool used to predict the risk of sepsis in patients outside of the ICU.

How accurate is the qSOFA score?

While qSOFA is a useful screening tool, it should be used in conjunction with clinical judgment and other diagnostic procedures.

Who should use the qSOFA score?

Healthcare professionals use qSOFA as a rapid assessment tool for patients at risk of sepsis.

What actions should be taken based on qSOFA results?

Patients with a qSOFA score of 2 or more should be further evaluated for potential sepsis and receive appropriate medical care.

Can qSOFA be used for all patients?

qSOFA is generally used for adult patients. Pediatric assessment requires different criteria.
