Abstract
A device and method for controlling a level of ventilatory assist applied to a patient by a mechanical ventilator measures, during patient's assisted breath, an inspiratory volume Vproduced by both the patient and the mechanical ventilator, an inspiratory volume Vcontributed by the mechanical ventilator, and an inspiratory assist pressure Pproduced by the mechanical ventilator. A first relation between pressure Pand volume Vand a second relation between pressure Pand volume Vare calculated. Using the first and second relations, a ratio is determined between pressure Pat volume Vand pressure Pat volume V, with volume Vequal to volume V, for a plurality of volumes Vand V. Values of Pare multiplied by the corresponding calculated ratios to calculate a third relation between a predicted inspiratory pressure Pand volume V. The mechanical ventilator is responsive to the third relation to control the level of ventilatory assist.
