Abstract
A method and system for measuring changes in inspiratory load of a patient's respiratory system during mechanical ventilation. The method and system calculate a first relation between a measured inspiratory airway pressure and a measured electrical activity of respiratory muscle, and a second relation between a measured inspiratory volume and the measured electrical activity. A load index is calculated from the first and second relations. Changes in inspiratory load are determined based on the load index.
