where Pprox(t) is the proxy pressure; PEEP is the extrinsic PEEP level; To is a time at which the pressure measured by the pressure sensor at the patient port reaches PEEP; Tf is a time at which an inhalation phase starts, Qlung(t) is the gas flow into the lungs measured by the gas flow meter; and Ctube is a tubing circuit compliance of the breathing tubing circuit.
