Key result
Density wave model of CPR explains rhythm criticality, excessive force failure, and AED synergy.
A novel physical model conceptualizes CPR as a forced density wave restart, providing a theoretical framework for resonance-optimized resuscitation.
Cardiac arrest represents collapse of the density gradient driving spiral cardiac motion (D→∞, V→0). CPR externally reimplants a rhythmic density wave, forcing ∇N to reform. This model explains why rhythm is critical (resonance), why excessive force fails (gradient homogenization), why AED synergizes (ionic gradient restoration), and why time decay is irreversible (substrate dissolution). Opens path to resonance-optimized resuscitation protocols.

Yoshimitsu Katayama (2026) studied Cardiac arrest. Cardiopulmonary Resuscitation (CPR) was evaluated. A physical model of CPR as a forced density wave restart explains the critical role of rhythm, the failure of excessive force, and the synergy of AEDs in restoring ionic gradients.
