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

  • monitoring a plurality of sensors including a first sensor and at least one second sensor to obtain first sensor measurements and second sensor measurements;

    fitting a curve for first sensor measurements versus time based on the second sensor measurements, 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 an estimate of first sensor measurements for a time interval based on the one or more fit parameters and the second sensor measurements; and

    displaying the estimate of the first sensor measurements for the time interval instead of the first sensor measurements.
