The Critical Care State Space Project is a new approach to ICU clinical decision support. These visual models represent a patient's condition as a position in a multi-dimensional constraint space — compressing the cognitive load of complex ICU problems into a single readable view whilst preserving traceability from the synthesis back to the source measurements and published evidence that defines each constraint.
Each axis of the visualisation encodes an evidence-anchored physiological constraint; each point on the polygon is a clinical state. A 24-hour temporal loop view extends the static snapshot to a trajectory — allowing direction and rate of change to be interpreted alongside the current state.
These are constraint-state-space visualisation models, not dashboards. Where a dashboard presents data, these models represent the patient's state within a defined physiological constraint space.
Two live interpreters are available below. Both implement manual scrubbing of the temporal loop, hourly quantisation of blood-gas-derived values, and a "worst-driver" composite highlight that makes the dominant constraint readily visible.
A three-axis polygon spanning mechanical power, oxygenation, and ventilation, with a parallel "drill-down" view for resistance, PEEP, and compliance. A dedicated dead-space panel grounded in the Enghoff modification of the Bohr equation surfaces the P(a−ET)CO₂ gradient and Vd/Vt as a differential-reasoning cue.
Open prototypeExtends the paradigm to continuous renal replacement therapy as a four-axis polygon covering volume balance, metabolic state, hemodynamic adequacy, and solute clearance. A circuit-and-filter schematic view offers a complementary spatial reading of filter health, anticoagulation adequacy, and transmembrane pressure.
Open prototypeResearch prototypes only. The interpreters are intended for educational and methodological exploration. They are not validated clinical decision-support systems, are not regulated as medical devices, and are not intended to substitute for clinical judgement. Methodological documentation is available under Approach; the conceptual references are listed under References.
