1. A method for estimating at least one parameter at a patient circuit wye in a medical ventilator providing ventilation to a patient, the method comprising:

  • monitoring at least one of ventilator settings, internal measurements, available hardware characteristics, and patient characteristics;

    extracting respiratory mechanics of the patient from ventilator data by fitting a curve based on at least one of the ventilator settings, the internal measurements, the available hardware characteristics, and the patient characteristics, wherein said fitting relies on one or more fit parameters, and wherein the values of said one or more fit parameters are found by said fitting;

    calculating a first estimate of at least one parameter at a patient circuit wye for a time interval with at least one sensor model based on at least one of the ventilator settings, the internal measurements, the available hardware characteristics, the patient characteristics, and the one or more fit parameters; and

    displaying the first estimate of the at least one parameter at the patient circuit wye for the time interval.
