Ventilator for mechanical ventilation, flow control and flow conditioning equipment associated therewith, and operating method of a ventilator for mechanical ventilation

Flow control and conditioning equipment for a ventilator for mechanical ventilation, said equipment (20) characterized in that it presents a tubular configuration comprising a plurality of connections (21, 22, 23, 24, 25) pneumatically communicated, with at least:

• an inspiratory inlet port (21) configured to connect to an inspiratory branch (Ri) and receive the air/oxygen mixture;
• an endotracheal outlet port (22), aligned with the inspiratory inlet port (21), configured to connect to an endotracheal tube (T) attached to the patient (P) and deliver a continuous flow (Fc) of the air-oxygen mixture to the patient (P);
• and
• an expiratory outlet port (23), arranged in a “T” between the inspiratory inlet port (21) and the endotracheal outlet port (22), configured to connect to an expiratory branch (Re) and allow the expiratory flow (Fe) to exit from the patient (P).

An operating method of a ventilator for mechanical ventilation, characterized in that it comprises the following steps:

• receive air and oxygen;
• condition a continuous flow (Fc) of such air and oxygen with controlled acceleration;
• and
• shock the accelerated continuous flow (Fc) with an expiratory flow (Fe), causing an expiratory brake and an intrinsic PEEP end-expiratory pressure.
