9-Keel Unified Theory Series: Paper 41 D(t) Imbalance Model for Severe Burns — Water Ledger Collapse and Systemic Homeostasis Failure

Severe burns represent a catastrophic form of acute systemic homeostasis collapse, characterized by sudden barrier damage, extreme metabolic drive, and rapid body fluid loss. This paper applies the 9-Keel D(t) dynamic imbalance index and Water Ledger theory to construct a quantitative theoretical model for severe burn progression. Using core vital signs (body temperature, blood pressure, heart rate, and arterial blood pH) as evaluation dimensions, weight coefficients are assigned to highlight circulatory instability and metabolic explosion. The 0.5℃ micro-temperature deviation is introduced as an early warning threshold. The D(t) model stratifies the progression into four stages: steady state, mild imbalance, compensatory failure, and systemic collapse. This study is a pure theoretical analysis and does not involve clinical diagnosis, treatment, or medical guidance. It further verifies the universality of the 9-Keel Unified Theory in severe physical injury scenarios.
