The object of the invention is a system with an electrically controlled source of gas flow or pneumatic power, comprising a block of calibration source of gas flow or pneumatic power connected pneumatically to the inspiratory section, a flow meter located in the inspiratory section, a microcontroller control block connected to the flow meter, comprising a flow meter calibration module, characterised in that the flow meter (131) is connected, on one side, between a first check valve (133A) of the inspiratory section and an inspiratory tube (134A) and its downstream second check valve (133B) of the inspiratory section and, on the other side, is connected between a third check valve (133C) of an expiratory section, connected to its downstream expiratory tube, (134B) and a shut-off valve (ZP), so that the flow meter (131) is located on a diagonal of a pneumatic bridge thus formed, and the calibration flow qi and the expiratory flow qe flow through the flow meter (131) alternately in the inhalation and exhalation phases in the same direction.
