Theory 13/Seconds to Minutes/Blood pressure
Pressure Stability Needs a Fast Reflex
The claim
Blood pressure stability is set by the ratio of baroreflex delay to the period of pressure oscillation, so a delayed reflex can amplify rather than damp an oscillation.
01Mechanism
Feedback with delay can oscillate; when the delay approaches the period, damping turns to resonance.
02Prediction
Oscillation should appear above a delay ratio.
03Refutation
Stability tracking reflex gain alone would remove the delay.
