APPARATUS FOR ASSISTED VENTILATION AND CORRESPONDING REGULATION METHOD

摘要

An apparatus for assisted ventilation (1) comprises at least one ventilatory block (2) connected to and controlled by a drive block (3), and at least one sensor block (4) connected to the drive block (3) and adapted to provide it with a signal of electrical activity produced by the diaphragm. The apparatus further comprises at least one calculation block (5) connected to the drive block (3), to the sensor block (4) and to the ventilatory block (2), the calculation block (5) receiving from the sensor block (4) a signal of diaphragmatic activity (Eadi) and from the ventilatory block (2) a ventilatory pressure signal (Paw) and providing the drive block (30) 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 block (2) so as to cause an expiratory pause.
