Theory 09/Respiratory cycle/Termination phase
Off-Switch Is Hysteretic
The claim
Expiration ends at a different threshold than the one that started inspiration, so the cycle has hysteresis set by lung compliance.
01Mechanism
Elastic recoil and airway resistance define different switching points for on and off.
02Prediction
On and off thresholds should differ.
03Refutation
Symmetric thresholds would remove the hysteresis.
