How the model works
Calculation order, equations, interactions, waveform generation and explicit assumptions.
Heart sounds, PCG audio, clicks, knock & tumor plop
Illustrative valve-event markers and optional synthesized audio share the cardiac clock.
How the simulator works
An indexed reference to the physiology, equations, traces and assumptions behind Circulation Studio.
Implementation index & documentation coverage
Find the modules responsible for each relationship and display.
Left atrial myxoma: mobile obstruction & tumor plop
A selected mobile-mass example shares beat-dependent inflow mechanics and sound timing.
LV and RV pressure–volume construction
Pressure comes from the trace; volume is an idealized, flow-conserving chamber model.
Measured summaries, units & rounding
Why a sampled mean, a baseline target and an end-diastolic point differ.
Mechanical support: flow paths, pressure & pulsatility
ECMO, Impella and IABP have different circulatory actions.
Multiple diseases: dominance, addition & constraints
How selected pathologies interact instead of simply adding their pressures.
Oxygenation, CO₂, perfusion & pleth
Synthetic gas exchange and pulse reliability are related but different.
PEEP, transmural pressure & cardiopulmonary loading
Why measured filling pressure can rise while useful preload and output fall.
Pericarditis: inflammation, transient constriction & resolution
Manually compare selected inflammatory states without predicting a patient’s course.
Postural maneuvers & Valsalva phases
Short-lived loading experiments use shared pressure, flow and reflex rules.
Pressure waveforms: atria, ventricles & arteries
Synthetic contours are anchored to the solved circulation and shared beat timing.
Pulmonary Hypertension: methods & interpretation limits
Simulator-derived pressure teaching, drug mechanisms, trial appraisal, PAH risk algorithms, connective tissue disease screening and guideline-based interpretation.
Reference phenotypes & baseline numbers
The starting catalogue is a set of teaching examples, not diagnostic criteria.
