1. A method for estimating effort of breathing of a patient, comprising:

  • receiving respiratory parameters of the patient;

    calculating, with a processor, respiratory data from the respiratory parameters;

    inputting the respiratory data into a mathematical model created using clinical data; and

    providing at least one output variable from the mathematical model corresponding to effort of breathing;

    wherein the mathematical model is a neural network trained to provide said at least one output variable, wherein the training of the neural network comprises clinical testing of a test population of patients using esophageal pressure as clinical data input to the neural network.
