Clinical decision support
Clinical intelligence for better patient decisions.
Find the right validated tool in seconds, see exactly how the result is calculated, and understand the evidence and limitations behind every number.
Clinical Navigator
Start from the clinical problem
Don't know the name of the score? Begin with the presentation and HumanPulse shows the relevant tools, when each is useful and its key limitations.
Chest pain
Risk-stratify adults with possible acute coronary syndrome.
Suspected pulmonary embolism
From pretest probability to rule-out and severity once PE is confirmed.
Atrial fibrillation
Balance stroke prevention against bleeding risk.
Head and neck trauma
Decide on imaging after minor head injury or possible cervical spine injury.
Acute stroke
Quantify neurological deficit and consciousness.
Pneumonia and sepsis
Severity, site of care and organ dysfunction in infection.
Kidney function and AKI
Estimate GFR, dose drugs and characterise acute kidney injury.
Liver disease
Cirrhosis severity, fibrosis triage and alcohol-associated hepatitis.

How it works
From patient data to a transparent answer
Find
Search by tool, condition or clinical question — or start from the problem in the Navigator.
Enter
Clear inputs with units, valid ranges and explanations. Nothing clinically important is ever guessed.
Understand
A prominent result with risk category, visual scale, score breakdown and plain-language interpretation.
Verify
Original publication, validation population, guideline status, limitations and version for every tool.
Evidence first
Built to be checked, not just trusted
HumanPulse never shows an oversimplified “accuracy percentage”. Instead, each tool explains who it was validated in, what it predicts, over what time horizon, and where it falls short.
Read our evidence methodology- Deterministic calculations
Every formula is implemented in tested code with published reference cases. - Versioned and traceable
Each result records the calculator version; formula changes are logged. - Transparent limitations
Populations, exclusions and known calibration problems are shown with the result. - No patient data by default
Calculations run without storing identifiable patient information.
