APPARATUS FOR ASSISTED VENTILATION AND CORRESPONDING REGULATION METHOD

摘要

An apparatus, for assisted ventilation (1), includes at least one ventilatory device (2) connected to and controlled by a driver (3), and at least one sensor device (4) connected to the driver (3) and adapted to provide it with a signal of electrical activity produced by the diaphragm. The apparatus further includes at least one calculation device (5) connected to the driver (3), to the sensor device (4) and to the ventilatory device (2), the calculation device (5) receiving from the sensor device (4) a signal of diaphragmatic activity (Eadi) and from the ventilatory device (2) a ventilatory pressure signal (Paw) and providing the driver (3) with calibration parameters (Cal) calculated on the basis of a signal of diaphragmatic electrical activity (Eadi*) and a ventilatory pressure signal (Paw*) upon switching-off said ventilatory device (2) so as to cause an expiratory pause.
