Abstract :
An algorithm that estimates the patient and ventilator work components of mechanically ventilated patients is presented. The algorithm requires the continuous measurement of inspiratory airflow rate and mouth pressure and it is suitable to be incorporated in ventilators for on-line estimation of the patient and ventilator contributions to the total work of breathing
