Embodiment Construction

[0048] With reference to these drawings, and in particular to figure 1 , the device for assisting ventilation realized according to the present invention is denoted as 1 as a whole. As will become clear from the continuation of the description, the device 1 for assisted ventilation is capable of implementing the method for regulation of assisted ventilation according to the invention.

[0049] The invention is based on the consideration that the electrical activity (Eadi) generated through the diaphragm is directly proportional to the muscle pressure (Pmusc) that determines the breathing activity of the subject, however, according to it is variable from one subject to another and cannot A previously predicted scaling factor to assess the effect on respiration, ie the subject's spontaneous breathing activity, from this muscle pressure (Pmusc).

[0050] Furthermore, it can be assumed that this proportionality factor will vary not only between different subjects (e.g., subjects ...

Abstract

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.

Description

technical field [0001] The invention relates to a device for assisting ventilation. [0002] The invention also relates to methods for the regulation of assisted ventilation. Background technique [0003] As is well known, artificial ventilation, also known as assisted ventilation or mechanical ventilation, replaces or supplements the activity of the subject's inspiratory muscles, supplying the energy needed to ensure an appropriate volume of gas to the lungs. [0004] In general, a distinction is made between permanent assisted ventilation and temporary assisted ventilation. [0005] Permanent assisted ventilation is usually performed with the aid of a negative pressure ventilation system, which uses an air chamber surrounding the chest cavity, such as an "iron lung", and which rhythmically introduces negative pressure to allow air to be drawn into the trachea and lungs. [0006] Temporary artificial ventilation is based on a positive pressure system, such as a respirator...
