LIPS Score Calculator
Lung Injury Prediction Score for ARDS Risk Assessment
The Lung Injury Prediction Score (LIPS) is a validated clinical prediction tool designed to identify patients at high risk for developing Acute Respiratory Distress Syndrome (ARDS).
LIPS assesses a patient’s risk of developing ARDS based on predisposing conditions and risk modifiers present at hospital admission or within the first 6 hours.
Understanding the LIPS Score
The LIPS is a weighted scoring system that helps identify patients at risk for ARDS before they actually develop the condition. Developed through a multicenter prospective cohort study and published in 2012, LIPS represents a significant advancement in preventive critical care medicine.
Clinical Significance
Early identification of high-risk patients allows clinicians to:
- Implement protective ventilator strategies preemptively
- Closely monitor for early signs of respiratory deterioration
- Consider targeted preventive therapies
- Improve resource allocation in critical care settings
Components of the LIPS Score
The LIPS incorporates multiple factors:
Predisposing Conditions:
- Shock
- Aspiration
- Pneumonia
- Sepsis
- High-risk surgery (aortic, cardiac, thoracic, abdominal, neurologic)
- Trauma (brain injury, lung contusion, multiple fractures, multiple transfusions)
Risk Modifiers:
- Alcohol abuse
- Obesity (BMI >30)
- Hypoalbuminemia
- Chemotherapy
- FIO2 requirement >0.35 (or >4L O2)
- Tachypnea (RR >30)
- SpO2 <95%
- Acidosis (pH <7.35)
- Diabetes mellitus (protective factor)
Scoring and Interpretation
- Score Range: -1.5 to 15 points
- Low Risk: <4 points (ARDS risk ~2-3%)
- Intermediate Risk: 4-6 points (ARDS risk ~7-9%)
- High Risk: ≥7 points (ARDS risk ~18-25%)
Clinical Applications
The LIPS score is particularly valuable in:
- Emergency departments for triage decisions
- Post-operative monitoring settings
- General medical wards for early warning
- Guiding enrollment for clinical trials of ARDS prevention
Limitations
- Does not account for all possible risk factors
- Performance may vary in different patient populations
- Should complement, not replace, clinical judgment
- Less validated in pediatric populations
Conclusion
The LIPS score represents an important step toward proactive rather than reactive critical care. By identifying patients at high risk for ARDS early in their hospital course, clinicians can implement preventive strategies that may reduce the incidence and severity of this devastating condition.

Clinical Interpretation
Based on the calculated LIPS score, the patient has a low risk of developing ARDS.
Recommended Actions
Standard monitoring and care are appropriate.

Important: The LIPS score is a prediction tool and should not replace clinical judgment. Always consider the individual patient’s overall clinical picture and trajectory.

What is the LIPS Score?
The LIPS is a weighted scoring system that assesses a patient's risk of developing ARDS based on predisposing conditions and risk modifiers present at hospital admission or within the first 6 hours. Unlike many scoring systems that predict outcomes after diagnosis, LIPS focuses on prevention by identifying at-risk patients early.
Clinical Significance
Early identification of high-risk patients allows clinicians to:
- Implement protective ventilator strategies preemptively
- Closely monitor for early signs of respiratory deterioration
- Consider targeted preventive therapies
- Improve resource allocation in critical care settings

- SpO2 <95%
- Acidosis (pH <7.35)
- Diabetes mellitus (protective factor)
Scoring and Interpretation
- Score Range:Â -1.5 to 15 points
- Low Risk:Â <4 points (ARDS risk ~2-3%)
- Intermediate Risk:Â 4-6 points (ARDS risk ~7-9%)
- High Risk: ≥7 points (ARDS risk ~18-25%)
Clinical Applications
The LIPS score is particularly valuable in:
- Emergency departments for triage decisions
- Post-operative monitoring settings
- General medical wards for early warning
- Guiming enrollment for clinical trials of ARDS prevention
