Abstract
A method, a computer program and a breathing apparatus relates to determination of at least one physiological parameter including the neuromechanical efficiency [NME] of a patient being mechanically ventilated by the breathing apparatus. This is achieved by obtaining samples of an airway pressure (P), a patient flow (Ø), a change in lung volume (V) caused by the patient flow, and an electrical activity of a respiratory muscle of the patient, during ventilation of the patient at a first level of ventilatory assist and a second and different level of ventilatory assist, and determining the at least one physiological parameter, including NME, from the airway pressure samples, the patient flow samples, the samples of the change in lung volume, and the samples of the electrical activity of the respiratory muscle, obtained at the different levels of ventilatory assist.
