1. A method for ventilating a patient with a ventilator comprising:

  • receiving a plurality of ventilator parameters;

    estimating a net value of patient muscle effort based on the received ventilator parameters, wherein the net value of patient muscle effort is estimated using a parameter estimate vector update equation to solve for a recursive least squares gain value representing the estimated net value of patient effort at a time instance by subtracting a squared gain value for a previous time instance multiplied by a regression parameter vector at the time instance and a transpose of the regression parameter vector at the time instance and a transpose of the squared gain value for the previous time instance divided the result by one plus the transpose of the regression parameter vector at the time instance multiplied by the squared gain value for the previous time instance multiplied by the regression parameter vector at the time instance from the gain value for the previous time instance; and

    calculating target inspiratory pressure based on the estimated net value of patient effort.
